Boston Consulting Group Senior Data Scientist interview questions

Screening test: Python and ML questions medium level. Needs medium level fast coding skills. Round 1 : Taken by Lead DS from outside India who is a very cool person. Came prepared for DS case round. Asked ML and Data questions. Listened very patiently Round 2: Some India Analytics Head. Came 10 min late to the Interview and ended up in 30 min, while this was scheduled for 1 hour. The person was not prepared with anything. Didn't have time to listen. Didn't ask a single proper question. Asked 2-3 discrete topics and used to end them abruptly. God knows what he was looking for.

first round is technical coding test. 4 rounds of interviews, all case studies. Interviews are good until the third one. Not very professional. Strange questions and got rejected directly without any feedback/reasons.
