Hiring team was good and arranged everything smoothly. Flew down to BKK for the loop. Here's where it went a bit weird. I have given PM interviews before at FAANG and not encountered such irrelevant questions. I expected to be asked around roadmapping, tradeoffs, analytics, case studies, data etc. However 2 out of the 4 interviewers asked me ONLY about solving a probability problem and one of them asked me how would I code a robot arm. Either they are looking for a different skill set or something else is an issue. I don't mind getting rejected but atleast ask relevant questions to the PM function. If indeed you want to ask such questions inform the interviewee.

I was told being shortlisted and asked to complete an online test which was 2.5 hours long at a stretch and quite exhaustive like a semi version of a GRE/GMAT. I felt it was unnecessary to put candidates to do this test prior to finding the mutual fit as in explain the position and find out if candidate is interested/fit for the opportunity. It's a complete waste of time for candidates without knowing if they have been seriously considered or just doing some HR assignment. HR also doesn't provide any feedback or test result post doing this test which is even more annoying, specially when one spends so much time and energy in writing such test.

Long and rigorous 10-interview process. Case studies are very difficult but applicable. Puzzle games... not sure I see the value. Interviewers are generally very nice and intelligent. Company did not fly me to interview, I volunteered but was not offered any compensation other than a taxi ride to the airport.
