Interviewers didn't seem to communicate with one another at all.
Two of the interviwers where very unprofessional, bad mouthing the employee I would have been replacing.
Scope of the job constantly changed from what was in the posting
Once of the interviews was double booked, wasn't informed until I was already in the office only minutes before the interview.
Four of the interviews were rushed to take place on one day, so had to take time off from a freelance gig. Lost $200 (Not directly their fault but didn't help overall experience).
Two phone screenings, Four Interviewers, and then Ghosted.
