Landing a job that you love can be tough, especially if you’ve graduated amidst a pandemic or during the global recession that followed it. Even for more experienced people, the landscape of the job market is at an unprecedented speed and the future looks uncertain. This blog outlines some basic tips that will position you ahead of the curve and increase your chances of getting hired.   

With scores of resumes in front of them, recruiters only spend a few seconds reviewing each resume and making a decision, so if you’ve landed an interview, you’ve probably done something right. However, the actual recruitment process is much longer and usually very rigorous to ensure that the candidate is a good fit for the company. Let’s look at some of the things you can do to improve the likelihood of getting an offer.  

 

Getting hired as a data scientist
Getting hired as a data scientist

 

1. Know the recruitment process 

Every company has a standard process for vetting candidates. This could vary for each company, but it is usually a mix of a few or all of the following components. It is important to note that all these components have a specific purpose and aim to understand different sides of you. 

  • Screening – This initial step is a short interview, usually with the recruiter, to evaluate your basic skills and to validate the qualifications mentioned in your resume. The most common questions are regarding your educational and work background, availability, salary expectations, and reason for applying for the job.  
  • Case studies – Some companies employ case studies to evaluate core knowledge and skills related to the job. They help employers identify how candidates manage uncertain situations, their logical and analytical reasoning, problem-solving skills, and creativity among other things.  
  • Intelligence testing – IQ tests commonly measure cognitive skills. A well-rounded candidate is expected to display not only technical but critical thinking capacities and IQ tests are standardized ways of measuring that. 
  • Panel interviews – To get a holistic understanding of a candidate’s capabilities, the hiring manager usually interviews them along with a few other teammates to not only assess their technical expertise but also if they would fit in with the company culture.  

 

Knowing what the recruitment process looks like at a company could help you in preparing for it better and reduce your anxiety about what will come next. Therefore, when an HR representative reaches out to you, always ask about the next steps and the average time to run the complete recruitment cycle.  

 

2. Do your research  

Before walking into the interview, learn all about what the company does, its background, and how it has grown in the past. A simple LinkedIn search could also lead you to posts by employees where you can learn about their experiences. More importantly, read the job description carefully, so you know what the role requires and how your experience can contribute to your success there.  

It also helps to know a bit about the interviewers, including their career history and role in the company. This will give you a good idea of the type of questions a particular interviewer will ask, i.e., technical or related to soft skills.    

 

3. Know what you are looking for 

One question that interviewers use to gauge how passionate you are about the position in hand, is, “Why do you want to work with us?”. While there may be many variations of this question, your answer needs to be personalized and authentic. Generalized answers like the prestige of the company and gaining work experience won’t cut it.

With all this information, you will be able to formulate a personalized answer to why you chose to apply to the company which may include the culture, growth opportunities, and specific industry leaders you might want to work with among others.  

Not only this but, it will also mean that you will be applying for the right reasons. Being clear about why you are working at a company will keep you focused and motivated. In general, keep a list of things you are looking for in a company and target those that you feel would provide those to you.

4. Prepare for different interview questions 

Prepping ahead of time plays a vital role in making you feel confident and ready for an interview. You may want to role-play with a friend to practice how you would respond to various prompts that might be asked of a data scientist. While it is impossible to know the exact questions that would be asked, you can dig deeper, prepare answers for frequent questions and not get tongue-tied in the interview. Different areas are assessed using the following diverse types of questions: 

  • Knowledge-based – These questions tend to be more direct and help to see if the candidate would be able to perform well at the job they are being hired for.  
  • Introspective – Companies want to hire self-aware people who not only know their strengths but also their weaknesses so they can work on them. Presenting a perfect self will not help here – it is important to reflect and be honest. 
  • Hypothetical – Using hypothetical scenarios, interviewers can assess your potential to make quick decisions and give them an insight into your process of getting there.  
  • Behavioral – Questions about how you handled certain situations in the past are behavioral questions. This gives the interviewers a sense of how you approach problems, conflicts, and relationships at work, which eventually helps them understand if you would fit into their team. 

 

5. Ask questions  

At the end of each interview, candidates are asked if they have any questions from the interviewers. This is a great opportunity to get more context on the role, the team, and the company and make an informed decision. Prepare a set of questions beforehand that could include areas like working hours, policies, team structure, or specifics about the function and role. 

As a data scientist, it is important to know about the projects you will be involved in working on. Learn about the expectations during the question-answer session in your interview.

Remember that this could be a future place of work for you, and you are evaluating it as much as the interviewer is assessing you. Moreover, it will help build your interest and motivation if it is the right place for you.  

 

6. Plan ahead for the day of the interview  

The way you act during the whole recruitment process, especially on the day of the interview, factors into your evaluation as a candidate. So, always stay professional, check your emails for errors before sending, and be courteous. For some things, you will need to plan:  

  • Your outfit for the interview to make a good impression, 
  • Being on time: if it is an on-site interview, make arrangements for transport,  
  • Check your internet connection and laptop battery for remote interviews,  
  • Choose a peaceful spot for virtual interviews, 
  • Have a wholesome meal and stay hydrated to avoid lethargy.  

 

7. Highlight your uniqueness  

It is easy for someone to check all the boxes for the requirements of a role, but out of many that do, only one has to be hired. So, what is it that helps you cut? Your genuineness and uniqueness. Every person has a different journey and distinct experiences meaning everyone has something different to offer. Being able to reflect on these to understand your unique superpowers and highlight them will help the recruiters see your real potential.  

To do this, answer questions with examples of what you have done in the past and how you faced challenges. For example, a fresh graduate may not have past work experience, but you may show how good you are at teamwork by talking about a time when you delivered a team project in college.

More importantly, don’t just say that you are willing to learn and come with a growth mindset, share tangible examples that showcase your curiosity and effort. Another great way to make an impression is to share something that is not explicitly mentioned in your resume. For instance, when the interviewer asks you to introduce yourself, talk about a multi-faceted you to bring your human side to light.    

 

Conclusion

Process Mining is a critical skill needed by every data scientist and analyst for mining rich and varied data contained in event logs.

Event logs are everywhere and represent a prime source of big data. Event log sources run the gamut from e-commerce web servers to devices participating in globally distributed Internet of Things (IoT) architectures.

Even Enterprise Resource Planning (ERP) systems produce event logs! Given the rich and varied data contained in event logs, process mining these assets is a critical skill needed by every data scientist, business/data analyst, and program/product manager.

At the meetup for this topic, presenter David Langer showed how easy it is to get started process mining your event logs using the OSS tools of R and ProM.

David began the talk by defining which features of a dataset are important for event log mining:

Activity: A well-defined step in some workflow/process.

Timestamp: The date and time at which something worthy of note happened.

Resource: Staff and/or other assets used/consumed in the execution of an activity.

Event: At a minimum, the combination of an activity and a timestamp. Optionally, events may have associated resources, life cycle, and other data.

Case: A related set of events denoted, and connected, by a unique identifier where the events can be ordered.

Event Log: A list of cases and associated events.

Trace: A distinct pattern of case activities within an event log where each activity is present at most once per trace. Event log typically contain many traces.

Below is an example of IIS Web Server data that may be used for process mining:

intro_event_log_meetup Process mining

 

In this example, the traces for this event log are:

  1. portal, dashboard, purchase order report
  2. portal, help, contact us
  3. portal, my team, expense reports

David proceeded his talk with a live demo using the Incident Activity Records dataset from the 2014 Business Processing Intelligence Challenge (BPIC).

About the meetup

In this presentation hosted by Data Science Dojo:• The scenarios and benefits of event log mining• The minimum data required for event log mining• Ingesting and analyzing event log data using R• Process Mining with ProM• Event log mining techniques to create features suitable for Machine Learning models• Where you can learn more about this very handy set of tools and techniques for process mining.

Process mining source code

David’s source code can be viewed and cloned here, at his GitHub repository for this meetup. To clean and process the dataset, he ran through his R script step-by-step. David installed the R package, edeaR, which was specifically used to analyze and the dataset.

After cleaning the dataset, he loaded the new .csv file into the process mining workbench tool, ProM, for visualization. The visualization created helped gain insights about the flow of incident activities from open to close.

The number of applications for data scientist programs has increased. With various online resources, is it necessary to take a university degree in Data Science?

Data Science is one of the fastest-growing fields, and the data shows this trend will continue into the near future. Data Science has become the backbone of many fields – it is the data science that helps us make sense of the information we collect during marketing campaigns, and it is the data science that helps us construct economic models that predict macroeconomic trends. It’s a field bustling with technological innovation, and people studying it will be at the forefront of multiple industries in the years and decades to come.

If you are someone who wants to join the ranks of data scientists, you have multiple ways of achieving your goals, including going to a university, taking online data science courses, and lastly self-learning. Which of these approaches is the best one? Is it still necessary to go to university to have the best prospects of landing a job? This article will answer these questions and help you decide how to approach this exciting new field.

chart-for-is-it-necessary-to-go-to-a-university-to-become-a-data-scientist_small
Data, graphs, and analytics

Why might you still need a university degree?

The days that universities were for diving into academic studies are long gone. The recent advances in technology and the plethora of online resources have made it extremely easy for motivated individuals to learn on their own.

Instead, the university is a place for you to socialize and network with influential people from your field of study. While we like to think we live in a meritocracy where people succeed by skill alone, that has never been true. It is not only about what you know; it is about who you know.

Your university will give you numerous chances to present yourself and your skills to eminent professors and influential people who’d be able to help you start a successful career. It is much easier to jump-start your career when you have direct access to employers instead of being one of the hundreds of online resumes, they receive each day.

The difficulty of getting the fundamentals right without an academic setting

Not all academic fields are created equal when it comes to online teaching platforms. There are certain fields of study like computer science and language studies that rely mostly on a passive intake of information, and that makes them excellent subjects to learn online.

Other subjects like philosophy and mathematics require methodological approaches and engaging extensively with professors and classmates, and these present significant hurdles for a self-learner. They’ll have to try harder to learn the concepts and follow the material if they want to learn these subjects, and many online learners aren’t motivated to do so.

While data science is looked at as a subfield of computer science, it requires a good grounding in the fundamentals of Calculus and extensive knowledge of statistics and probability. Due to the field’s heavy reliance on math, an online learner might have trouble handling the subjects.

A good university will provide you with receptive professors and like-minded fellow students that’ll help you engage with the harder subjects and stay motivated.

Innovative approaches making universities obsolete

While self-study textbooks and online video courses have been on the market for decades now, a wave of innovations in teaching methods is starting to threaten our traditional institutions, and the top two approaches, which might prove to be more effective than universities, are interactive learning platforms and gamified learning:

Interactive learning platforms

These were developed in the hopes of making the online learner more proactive. Studies have shown that passively listening to online courses without participation isn’t an effective method of learning.

If you use these platforms, you won’t just learn what a piece of computer code does, but you’ll be asked to use it to solve a problem. You won’t just be told about price equilibrium in Economics, but the platform will tell you to explain a system using the theory. This way you will be able to immediately apply the knowledge you’ve acquired, which makes learning the fields like economics and mathematics much easier.

Gamified learning

One thing the last decade has shown us is how effective games are in capturing people’s attention and gluing them to their seats. That’s why some educators and psychologists have done extensive research to help bring over some aspects of gaming to education.

Correct use of gaming principles in a learning system will make it easier for you to focus on learning more, retain more of the information, and feel less fatigue after long studying sessions. While this method is still in its infancy, it is already showing great promise.

The show, don’t tell: How can you start a career as a data scientist

While choosing to opt out of enrolling in a university might prevent you from networking, and it is really hard for online resumes to help you stand out, there are new ways and platforms where you can show your skills!

Competition Sites

Competition sites like Kaggle provide an excellent training ground for budding data scientists to show their skills. They provide competition from diverse fields from economics to computer vision. The people who come up with the best algorithms not only get monetary rewards, but they have a great chance of getting job offers. Most employers will be impressed if you achieve good results in these competitions as it shows a practical understanding of the field beyond academics.

Github and Jupyter Notebooks

Github and Jupyter Notebook allows you to present data analyses in a readable and concise format. Instead of boring old CVs, employers are more receptive to a rich portfolio. Thanks to the tools being completely free and intuitive to use, you’re only limited by your skills when it comes to the projects you tackle. You can build an amazing portfolio from the comfort of your home.

Conclusion

The answer isn’t cut-and-dry, and while there have been some movements claiming universities have become completely redundant in 2018, there are still some real benefits to them. You should ask yourself if you’d thrive in an academic setting, if yes, then you’d probably see sizable benefits from attending university. On the other hand, the new approaches to learning and portfolio building have made it easier than ever to succeed on your own, and you can do it if you are motivated enough.

Kaggle is the world’s largest community of data scientists and offers companies to host prize money competitions for data scientists around the world to compete in. This has made it the largest online competition platform too. However, Kaggle has started to evolve itself to organize offline meetups globally.

One such initiative is the organization of Kaggle Days. Up till now, four Kaggle Days events have been organized in various cities around the world, the recent one being in Dubai. The format of Kaggle Days involves a 2-day session consisting of presentations, practical workshops, and brainstorming sessions during the first day followed by an offline data science competition the next day.

For a machine learning enthusiast with intermediate experience in this field, participating in a Kaggle-hosted competition and teaming up with a Kaggle Grandmaster to compete against other grandmasters was an enjoyable experience on its own for me. I couldn’t reach the top ranks in the data science competition, but competing with and networking with the dozens of grandmasters and other enthusiasts present during the 2-day event boosted my learning and abilities.

I desired to make the best use of this opportunity, learn to the utmost extent I could, and ask the right questions from the grandmasters present at the event to get the best out of their wisdom and learn the optimal ways to approach any data science problem. It was heart-whelming to discover how supportive they were as they shared tricks and advice to get to the top position in data science competitions and improve the performance of any machine learning project. In this blog, I’d like to share the insights that I gathered during my conversations and the noteworthy points I recorded during their presentations.

Strengthen your basic knowledge of Kaggle

My primary mentor during the offline competition was Yauhen Babakhin. Yauhen is a data scientist at H2O.ai and has worked on a range of domains including e-commerce, gaming, and banking, specializing in NLP-related problems.

He has an inspiring personality and is one of the youngest Kaggle Grandmasters. Fortunately, I got the opportunity to network with him the most. His profile defied my misconception that only someone with a doctoral degree can achieve the prestige of being a grandmaster.

During our conversations, the most significant advice that came from Yauhen was to strengthen our basic knowledge and have an intuition about various machine learning concepts and algorithms. One does not need to go extensively deep into these concepts or be extra knowledgeable to begin with. As he said, “Start learning a few important learning models, but get to know how they work!”

It will be ideal to start with the basics and extend your knowledge along the way by building experience through competitions, especially the ones hosted on Kaggle. For most of the queries, Yauhen suggests, one must know what to search on Google. This alone will prove to be an extremely handy tool on its own to get us through most of the problems despite having limited experience relative to our competitors.

Furthermore, Yauhen emphasized how Kaggle single-handedly played a leading role in heightening his skills. Throughout this period, he stressed on how challenges triggered him to perform better and learn more.

It was such challenges that provoked him to learn beyond his current knowledge and explore areas beyond his specialization, such as computer vision, said the winner of the $100,000 TGS Salt Identification Challenge. It was these challenges that prompted him to dive into various areas of machine learning, and it was this trick that he suggested we use to accelerate career growth.

Through this conversation, I was able to learn the importance of going broad. Though Yauhen insisted on selecting problems that target a broad range of problems and cover various aspects of data science, he also suggested limiting it to the extent that it should align with our career pursuits and make us realize if we even need to target something beyond what we are ever going to use.

Lastly, the Grandmaster in his late 20’s also wanted us to practice with deep learning models as it’ll allow us to target a broad set of problems to discover the best approaches used by previous winners and to combine them in our projects or competition submissions. These approaches could be found in blogs, kernels, and forum discussions.

Remain persistent

My next detailed interaction was with Abhishek Thakur. The conversation provoked me to ask as many questions as I could, as every suggestion given by Abhishek seemed wise and encouraging. One of the rare examples of someone crowned with 2 Kaggle Grandmaster titles, competitions, and discussion grandmasters, Abhishek is the chief data scientist at boost.ai, having once attained the 3rd rank in global competitions at Kaggle.

What made his profile more convincing was Abhishek’s accelerated growth from a novice to a grandmaster within a year and a half. He started his career in machine learning from scratch and took this initiative from Kaggle itself. Initially starting with the lowest rank in competitions, Abhishek was adamant that Kaggle could be the only platform one could totally rely on to catapult his growth within such a short time.

However, as Abhishek repeatedly said, it all required continuous persistence. From the beginning until now, even after being placed in the bottom ranks initially, Abhishek carried on and demonstrated how persistence was the key to his success. Upon inquiring about the significant tools that led him to get gold in his recent participation, Thakur emphasized immensely on feature engineering.

He insisted that this step was the most important of all in distinguishing the winner. Similarly, he suggested that a thorough exploratory data analysis can assist one in finding those magical features that can enable one to get the winning results.

Like other Grandmasters who have attained massive success in this domain, Abhishek also emphasized improving one’s personal profile through Kaggle. Not only does it offer you a distinct and fast-paced learning experience, as it did for all the grandmasters at the event, but it’s also recognized across various industries and major employees who value these rankings. Abhishek told how it enabled him to get numerous lucrative job offers over time.

Start instantly with data science competitions

On the first day, I was able to attend Pavel Pleskov’s workshop on ‘Building The Ultimate Binary Classification Pipeline’. Based in Russia, Pavel currently works for an NLP startup, PointAPI, and was once ranked number 2 among Kagglers globally. The workshop was fantastic, but the conversations during and after the workshop intrigued me the most as they mostly comprised tips for beginners.

Pavel, who quit his profitable business to compete on Kaggle, Pavel insisted on the ‘do what you love’ strategy as it leads to more life satisfaction and profit. Pavel told us how he started with some of the most popular online courses on machine learning but found them lacking practical skills and homework, which he covered using Kaggle.

For beginners, he strongly recommended not to put off Kaggle contests or wait until the completion of courses, but to start instantly. According to him, practical experience on Kaggle is more important than any other course assignment.

Some other noteworthy and touching tips from Pavel were that to win such competitions, unlike many students who approach Kaggle as an academic problem and start creating fancy architectures and ultimately do not score well, Pavel approaches a problem with a business mindset. He increased the probability of success by leveraging resources, such as including people in his team who had resources, like a GPU, or merging his team with another to improve the overall score.

Upon an inquiry related to keeping the right balance between taking time to build theoretical knowledge and using that time to generate new ideas, Pavel advised looking at forum threads on Kaggle. They can help you know how much theoretical knowledge you are missing while competing with others.

Pavel is an avid user of LightGBM and CatBoost models, which he claims have given him superior rankings during the competitions. One of his suggestions is to use the fast.ai library, which, despite receiving many critical reviews, has been a flexible and useful library that he mostly keeps in consideration.

Hunt for ideas and rework them

Due to the limitation of time during the 2-day event, I was able to hear less from another young grandmaster from Russia, coincidentally sharing the same first name with his fellow Russian grandmaster, Pavel Ostyakov. Remarkably, Pavel was still an undergrad student then and has been working for Yandex and Samsung AI for the past couple of years.

He brought a distinct set of advice that can prove to be extremely resourceful when one is targeting gold in data science competitions. He emphasized writing clean code that could be used in the future and allows easy collaboration with other teammates, a practice usually overlooked which later becomes troubling for participants. He also insisted on trying to read as many forums on Kaggle as one could.

Not just ones related to the same competition but those belonging to other data science competitions as well since most of them are similar. Apart from searching for workable solutions, Pavel suggested also looking for ideas that failed. As he recommended, one must try using (and reworking) those failed ideas as there are chances they may work.

Pavel also brought up the point that to surpass other competitors, reading research papers and implementing their solutions could increase your chances of success. However, during all this time he stressed a lot on to have a mindset that anyone can achieve gold in a competition, even if he/she possesses limited experience relative to others.

Experiment with diverse strategies

Other noteworthy tips and ideas that I collected while mingling with grandmasters and attending their presentations included those from Gilberto Titericz (Giba), the grandmaster from Brazil with 45 Gold medals! While personally inquiring about Giba, he repeatedly used the keyword ‘experiment’ and insisted that it is always important to experiment with new strategies, methods, and parameters. This is one simple, although tedious, way to learn quickly and get great results.

Giba also proposed, that to attain top performance, one must build models using different viewpoints of the data. This diversity can come from feature engineering, using varying training algorithms, or using different transformations. Therefore, one must explore all possibilities.

Furthermore, Giba suggested that fitting a model using default hyperparameters is good enough to start a data science competition and build a benchmark score to improve further. Regarding teaming up, he repeated that diversity is the key here as well, and choosing someone who thinks similar to you is not a good move.

A great piece of advice that came from Giba was to blend models. Combining models can help improve the performance of the final solution, especially if each model’s prediction has a low correlation. A blend can be something as simple as a weighted average. For instance, non-linear models like Gradient Boosting Machines blend very well with neural network-based models.

Conclusion

Considering the key takeaways from the suggestions given by these grandmasters and observing the way they competed during the offline data science competition, I noted that beginners in data science must use their efforts to try varying methodologies as much as they can.  Moreover, a summary of the recommendations given above stresses the significance of taking part in online data science competitions no matter how much knowledge or experience one possesses.

I also noted that most of the experienced data scientists were fond of using ensemble techniques and one of the most prominent methods used by them was the creation of new features out of the existing ones. This is what was cited by the winners of the offline data science competition as their strategy for success. Conclusively, these sorts of meetups could enable one to interact with the top minds in the field and gain the maximum within a short time as I fortunately did.
