A LinkedIn recruiter contacted me for the position and did a 20-25 minutes long phone screening. Then the recruiter setup a technical phone interview with a machine learning engineer from LinkedIn's Sunnyvale office. The technical interview was quite challenging. The interviewer started with a self-introduction and continued with "tell me about yourself" type of questions. Next, I had 20 minutes coding problem regarding an algorithm development. Last, I got questions regarding explaining inner workings of a machine learning algorithm and case based questions regarding that algorithm (e.g., assume you have low accuracy in testing set ...). While tried helping me in the process, I found the interviewer a bit disrespectful. A lot of times, my responses were interrupted. The recruiter, on the other hand, was really kind and positive. In the end, I didn't proceed with the next step.

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.
