I had to go through a 5 stage process: first HR screening, then case study, then manager interview, then tech lead interview, then director-level interview. The process was quite quick (1 month overall) and the recruiter was very clear in explaining what the next steps would be and how to prepare. The interviews are quite simple for someone who has past Product experience, as they mostly focus on situational questions that a PM/PO has dealt with before. Each interviewer has their own twist and some ask small case studies during the interview itself, but these are all manageable. Overall, the process was very smooth.

5 rounds in total 1st round is HR - standard questions about previous experiences, salary expectations etc. 2nd round was with the Director, which the PO reported into 3rd round was with the Engineering Director that the PO's team collaborated with 4th round was with the Marketing Manager that the PO's team collaborated with 5th round was with the manager of the Director in the 2nd round.
