I had an interview with the talent recruiter and then moved onto completing a writing exercise answering fake support tickets. I was moved to the next stage with an interview with the hiring manager. I knew the second the interview started that it was not going to end positively as our personalities completely clashed so it wasn't a good fit for either of us. Found out 2 days later that I wasn't moving forward, which wasn't a surprise. It was a lengthy process, but for the right person I'm sure it would be okay.
