Tiger Analytics Senior Data Analyst interview questions

First round - Python Second round - SQL Third Round - Case study Fourth Round - Behavioral The overall process was quite seamlessly and fast paced without having to wait too long between rounds.

Initially I was contacted by HR requested me to attend the interview, I refused but she convinced me to attend. First online test both aptitude and technical round which contains Advance Python, SQL, Big Data Analytics and Hadoop related questions. Next round direct technical interview from team member. He given lot programming tasks in Python and complex SQL Queries. I have cleared both rounds on top. the final round is managerial round he is very polite but asked the proprietary Machine learning algorithms, codes and datasets which I have written for various projects in my current company. I refused politely and try to answer generally and explained the concepts also explained how I perceived those ideas precisely. But he was not satisfied which I come to know at the end of interview. Silent for almost 1 week no communications from HR. I have called them they said you are not fit. I told them I have cleared all rounds at least you should have a courtesy to properly inform me with valid reason, may be you have multiple candidates and chose someone else who are also got finished all rounds. Very Bad Experiance. now a days if any HR called first thing I asked them about is company culture.
