There was one interview with HR, one interview with hiring manager, then a series of interviews with hiring manager's counterparts and other leaders in that functional area that would be interacting with this role.
I made it to the final round and was completely ghosted - ignored two follow-ups to check on status. The role was removed from their website and I didn't even receive an automated message rejecting me. Incredibly unprofessional to make it to the final round and get zero followup, rejection, nothing. Stay away.
