Interview process
I was first contacted by the recruiter for a buisness DS position and had a quick screen. They walked me through the several rounds and what is covered in each. Later on they even helped me go through feedback for each round.
Had a total of about 5-6 rounds. The rounds were mostly case study and statistics oriented. Had very little ML depth questions.
