Tell me about yourself, provide a laptop, give some dummy data and ask to you to analyze. But interesting fact, they them selves are not data scientist, no real time practice, and want to understand from you how you do it, so that they can take it and use it in their day to day work. Complete cheating process to know the subject, and they will never offer you as their is no real time requirement. And Bengali Babu from BI background head the CoE, what a shame.
