Interview Preparation Tips

Round: Resume Shortlist
Experience: CGPA and background in data science were considered

Round: Test
Experience: We did not have a test as the company registered late. But from next time, they are definitely going to conduct a test. One can expect questions on probability and machine learning.
Duration: 1 hour

Round: Technical Interview
Experience: Any technical interview would mostly start with "walk us through your resume". The rest of the interview depends on how you drive their focus on to your spikes in resume. I was the winner/finalist in three pan-India data science competitons and authored a techinal paper on machine learning/ predictive modeling. I was asked to explain my approaches and the math/principle behind the working of Random forests, differences between XG Boost and Adaboost algorithms. You can expect these kind of questions if you mention such algorithms.


Tips: Know your resume inside-out. If you mention courses like machine learning or time-series analysis, you will be asked to explain algorithms using math equations. If you mention programming languages you will be asked to write a code.

Do not forget to ask questions at the end of the interview. It is the golden opportunity to gain brownie points.




Round: Technical + HR Interview
Experience: They asked me to start off by explaining any one of the projects that are relevant to the profile. While I was explaining, they asked many questions on data preprocessing, model building and model validation techniques. Later, I was asked three puzzles on probability and number theory. Then I was asked typical HR questions like "Why our company?". They asked me if I would consider pursuing masters in data science.




Tips: The amount of grilling is directly proportional to the stuff on your resume. Since I had competitions and a publication, I was properly grilled on basics of ML. But, this is not the case with other selected candidates. However, you would be definitely asked many questions/puzzles on probability.

Confidence and attitude are the major qualities you need to carry with you while attending an interview. Be firm with your answers. They should be simple and to the point. Make sure that your answers to questions like "tell us about yourself" and "walk us through your resume" are open-ended. You should leave hints about your spikes and then the interviewer comes in your way asking questions on your spikes.
