It was actually a round with the CEO.
I don't feel disrespected or anything, just feels weird to spend that much time interviewing someone.
I would take that very positively actually. At least you got feedback, and from the CEO! It seems to be you performed pretty well! Maybe the 'hopping' was the only distinguishing thing between you and the one that succeeded.
Reminds me of the 6 interview gauntlet I dealt with when interviewing with Hashicorp[1] years ago.
