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.

Phone interview: 1 coding questions followed by 1 machine learning related question The interviewer started with a self introduction and ask me some behavior questions about what my daily routine is and why interested in working in linkedin. Then we started the coding question using Skype pad for about 20 minutes. After I finished it, he asked me to do some unit testing to cover each edge case. Then we went through the machine learning related questions for about 20 minutes.
