What is the most amount of interviews at the same company you had to suffer through to land a job?

I was interviewing for two years before I landed a job that fit my needs. This was OK though because I was currently employed so I took my time. Some Companies only had two interviews, most three, but the most amount of interviews I had at an employer was eleven. That’s actually the job I have now so it was worth it. Eleven is completely ridiculous, however all we’re remote so I dealt with it. What has everyone else’s experience been like as far as a number of interviews?
