The original interview process was for 3 rounds, I was asked to do a 4th round because they felt I would be a better fit for product owner technical and not product owner UX, and I bombed the 4th round. Show a lot of ambition and confidence through out the process. They are known the repeat the same questions, scourge the internet for the latest questions and practice.
I enjoyed talking to all the interviewers. They were helpful and respectful throughout the process, nudged me in the right direction. It felt more like a conversation than an interview.
