Airbnb Project Manager interview questions

I only progressed to second round with a team member. 1)recruiter call with basic introduction, why Airbnb, 2) first round with hiring manager with deep dive in resume and one product case, 3) second road with another PM. with deep dive in how to set metrics and goals

I was given a take home project before the interview which I was expected to spend between 20-40 hours on. I could see the other candidates who were interviewing for the position on the shared Google Doc. When it came time for the actual onsite, only one person actually attended (out of the group of 8 I had been told would attend. I was never given a reason why I wasn't offered the role, but I was a lot more qualified than the other 2 candidates I knew were interviewing, and likely would have been a much more expensive hire if they had wanted to make a competitive offer. All in all, given their recent layoffs I think it all worked out for the best!
