As someone who just transitioned to data science, it was hard for me at times to determine what I should focus on to get a first job that fits my strengths. After conducting an initial interview with me, Sundeep created a personalized plan for me to prepare for my data science interviews. He was extremely professional throughout the process. I was able to use some of his suggestions to get my first Data Science job. Would contact him again in the future for the next steps of my career.

Sundeep is a great mentor and always ready to listen, give support and recommendations whenever needed. I worked with him during my internship at Swiggy. His experience and knowledge are priceless. His inputs were very influential throughout my project. He taught me to think like a researcher. His feedback helped me to grow not only professionally but also personally. I've been lucky enough to have him as my mentor in the early stage of my career. I would strongly recommend him for mentorship


- Sachin

Sundeep has been a wonderful mentor, and has always directed me to consider multiple aspects while looking at a situation - technically as well as at an inter-personal level! I have known him for about 2 years now, and he has helped me think critically while formulating an ML (research) problem, to meticulously analyze data, results, papers etc and much more! It was often fascinating to see the amount of time he would spend on giving detailed all round (technical, presentation, writing) feedback


- Rohan

I find Sundeep very approachable as a mentor. I received valuable mentorship from him while I was looking for internships. It was also very helpful to discuss with him plans for my career path and picking a specialization in my field. I was also able to learn a lot from his experiences in different work cultures, work opportunities in US and India, working for startups or bigger companies. Highly recommended!


- Edwin

Sundeep is a very personable! Sundeep helped me with job interview preparation. I had a really great experience working with Sundeep! He spent time understood what are my expectations for the session and gave professional advice on which skills to be deep dived for a better use of time. I was able to hear feedback on my areas of improvement and learned from the questions he asked. It was a SUPER helpful and VALUABLE coaching session for me. Thank you very much Sundeep!


- Sophia

Sundeep is really experienced at approaching Amazon leadership principles questions and helped greatly in preparing my behavioral interviews.


- Marina

Sundeep acted both as my first (mock) technical interviewer, after my bootcamp, and advisor. For a few rounds, he presented me with typical coding challenges asked at FAANG. His critique was tough, but he was generous with feedback and even some pointers on improvement and the path to get to the next level. It was very valuable to have such 1:1 input during coding from someone already in the industry.


- Veronica

Sundeep was a great mentor for preparing me for FAANG-level data scientist interviews. He is an expert on ML and product management, so I was able to learn a lot about his frameworks and tips, which were ultimately useful for my actual onsite interviews. Thanks to him, I received an offer from a FAANG company.


- Kensen

Sundeep provided me high-quality mock interview sessions specifically tailored around my Twitter DS interview I was gonna face. Sundeep is very knowledgeable in what he's doing and asked very interesting questions around many ML topics as well as relevant product and Stats questions, which helped me understand the nature of the interviews as well as explore more into the topics. Sundeep's feedback was spot-on and very much actionable. I ended up getting the offer from Twitter for Senior DS role.

Behavioral questions or leadership interview questions are probably the most frequently asked questions during a job interview.

However, I've interviewed so many talented data scientist candidates at a FAANG company. Some of them are very smart, did really well answering technical and coding questions, but they still didn't get their dream job offers. Why?

Because they didn't prepare behavioral questions and didn't know how to answer them,  which in the end, cost them their dream jobs!

Trust me, even if you are only interviewing for a technical job, behavioral questions still matter significantly, and you need to be well prepared, don't ever overlook them.

Behavioral questions may sound intimidating, and some of the questions may catch you off guard or even annoy you if you are not seen them before

But if you follow the strategy outlined in this tutorial and keep practicing those 9 types of behavior questions, you will nail them in your job interview.

Data modeling is often asked for data engineer, data warehouse architect, or software engineer positions.

Good data modeling is essential for a consistent, efficient, bug-free, and long-lived data environment.

Make sure you are super familiar with concepts such as Dimensional   Modeling Star  Schema,  Snow-Flaked  Schema.

It’s possible to solve any given data request in an almost limitless number of ways, but when data needs to be extensible and maintainable throughout the systems, a good data model is critical to success. When it comes to handling a business requirement with an ability to handle large data,  a  deeper understanding of normalized  (Third  Normal  Form)  and denormalized design.

Machine learning-related roles, including Research Scientist (Amazon, Google), Data Scientist / Algorithm (Facebook), and Machine Learning Engineers, are highly paid. Super fun often involves working with state-of-the-art algorithms.

The hiring process could be highly competitive. Not only will you be asked to be an excellent programmer (easy, medium levels of algorithm questions for sure), but you also need to know machine learning theories and experiences such as model parameter fine-tuning.

You will want to brush up on your machine learning skills if you want to succeed in a data science interview. A good place to start is with Andrew Ng's Coursera Machine Learning course.

You may also be asked topics such as CNN, NLP, reinforcement learning, computer vision, depends on the specific roles.

Deep Learning, The topic of deep learning, is in high demand in the data science world, and it is one of the key things that you want to brush up on if you are interested in pursuing a career in data science. There are a couple of good courses that you can check out, like Stanford's CS231n course.

Natural Language Processing (NLP) is an area in data science that is in high demand and will only become more so as we move further into the 21st century. NLP allows us to analyze text, whether spoken or written and derive useful information from it. If you want to be a successful data scientist, you want to work with NLP. This is a great area to pursue as a side project.

One of the data scientists’ main responsibilities is to extract insights from data and work with product managers and engineering teams to deliver actionable plans to improve the product. Think about how you would measure the success of different parts of the product. Why do you think the placement of the text box is at that specific location? What can you do to improve it?

The interviewer will try to evaluate your ability to apply data to the real product problem, how you systematically approach and structure the problem, form a hypothesis with reasonable assumptions, design, and test hypotheses through A/B testing, and use data and facts to convince others to adopt your recommended approaches.

Sample questions

  • If revenue dropped in a given week, what metrics would you look at to understand and why?
  • How would you measure the health of our product search functionality?
  • How would you measure the success of Uber Eats' search bar? How can we improve it? If we move the search bar to a different position, what metrics can we use to evaluate their performance? How would you convince the product manger to move forward with your design of the experiment?

System design questions are commonly asked during software engineer and data engineer interviews.

When interviewing at top technology companies, very often you will demonstrate your skills and abilities to convert a prototype into a large-scale, internet application.

System design takes many years of real work experience to be really good at it, and to a large degree, your performance in system design can determine your 'seniority' or 'levels' for your overall offer package.
