Colloquio
Phone screen then onsite.
Phone screen: 1 coding question and 1 question regarding precision/recall.
Onsite (6 rounds): 2 coding, 1 product design, 1 ML theory, 1 lunch, 1 behavioral.
They asked a lot of questions in ML theory round.
Recruiter's feedback: 1. I could not answer "what is '1' in F1 measure?" 2. I just describe superficially. Actually, I started thorough descriptions at the very beginning but the interviewer stopped me.
Seemingly, the interviewers are biased toward people from Statistics or a certain country.
