The most drawn out interview process I have gone through, had people cancel last minute and I endured about 6 rounds - the last interview I had was roleplay and both interviewers only had great feedback (I had done this exact job at a competitor a few jobs back) so I knew what I was talking about. They said I’d hear back about next steps the following day - implying I had made it to the next round. I chased them up for 3-4 weeks and finally got a generic email saying I wasn’t chosen. Absolute waste of time.
