4 rounds of interviews.
first interview was with their recruiter (She mentioned she was internal).
Second and third interviews were exactly the same but with different people. (Could have saved time with better coordination on their part)
final round was a mock call.
After this process, I was told they would move forward with other candidates because I did not have any industry experience. I think this should have been obvious from the first interview, and they should not have wasted three more hours afterwards.
I also got an alert shortly afterwards that they re-listed the same job.
