The most important part of an apology is, imo, sincerity. I think Patrick is chiming into this thread to perform damage control, not to sincerely apologize.
This, to me, is evident in the fact that OP interviewed for a specific, high level position, and named specific, repeated bad processes that go beyond Patrick's generic "We interview a lot of people so some people are going to have a bad time."
Patrick has more than enough information to start fixing things on a systemic level. Instead, he optimizes for the appearance of contrition without committing to fixing any of the specific problems mentioned.
