Interviewed with recruiter and client rep, then had an interview with hiring manager at AirBnB. Their assistant scheduled an interview, then they kept rescheduling it - once even on a Sunday. The recruiter claimed it was the scheduling software, then the manager's changing schedule, then the assistant's fault, etc. At the interview the hiring manager didn't even apologize - perhaps wasn't even aware. Regardless, it was a very unprofessional experience.
