The recruiter responded very quickly and the interview questions were around average difficulty. One of the questions I got asked was on Glassdoor and after asking around to other people who interviewed at Airbnb, it seems like they got the same questions. They did not ask about my background or any other technical questions, it was just the 1 coding question per interview (I had 3 Skype calls that were 45 minutes each). Recruiters are very friendly, but the interviewers did not seem to want to be there and it was hard to understand them.
