Interview Preparation Tips

Interview preparation tips for other job seekers - My advice would be to search on Google regarding "100 data science interview questions" or something like it, and as you go through each question and its answer, just search the Wikipedia or Google for each concept for a little more depth. As for Python coding questions, most questions in such interviews are asked only about the Pandas library of Python. So try to study how to use Pandas to manipulate data. A good reference is the Python For Data Analysis book by Wes McKinney, whose free PDF is most probably available online on Google.

Interview Preparation Tips

Interview preparation tips for other job seekers - Took 2 interviews over the course of 2 weeks and then 1 hour before my scheduled final / HR round declined to hire me as they decided that they don't want to.
Utter disregard for a candidate's time and work. The humiliating level of such degraded professionalism that they cannot decide before posting an interview that they don't want to hire.
But they have the audacity to expect 7 days and open-ended work schedule from the candidates.
DO NOT APPLY.
