Got opportunity via recruiter. There was a tech screen followed by Onsite. Tech Screen included background questions, experience questions as well as coding on collabedit space. The interviewer was helpful and gave prompts for answering the question. Was expected to give executable code with no syntax errors.

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.
