I applied through other source. The process took 5 weeks.

Five stages of interview. I only got to stage four. First stage was just a Q&A with the recruiter. Technical stages followed this. The first stage was about 30 minutes and every subsequent stage was an hour long. Everything went as expected for the pair programming interview. Two interviewers were present.

The system design interview seemed easy at first, but the two interviewers contradicted each other. One was very combative and pushed for me to move on to other sections when I wasn't ready. The same interviewer pushed for a needlessly complex design whilst the other just wanted something that would meet the problem requirements.

The product mindset interview focused much harder on soft skills. They asked some questions about my previous job but didn't seem to understand what it was that I had worked on. They also asked about how I would measure success for their team. I felt I didn't have enough information about their product to do this and they didn't seem happy with the metrics I was able to come up with from the information that I had.

The recruiter was quick to give detailed feedback but you don't get any feedback on why you failed the interview.

1. Pair programming, asked to implement a class based on given requirements.

2. System design, asked to design a system capable of serving a task described by the interviewer.

3. Product mindset, Q&A with a single product manager. Asked to come up with metrics for their product to measure success.
