The first round was some kind of Game where you had 15 MCQ questions relating to basic ML and stats. After couple of days, recruiter calls and sets up an interview suddenly on spot with some business analyst who has recently became a Data scientist. The questions were mostly relating testing and basic ML. The interviewer was wrong in asking questions and lacks ML understanding but was relatively better in Stats. No need prepare NLP and Deep learning as the company or the interviewer doesn't implement it.
