What made it a poor experience was that after 6 rounds I was kept warm for a week and then completely ghosted. That was a long process and a lot of interviewing to be totally ghosted at the final stage. I wouldn't imagine that I'd be a top candidate and have made it that far, to be left without any sort of feedback or a courtesy notification that I was not getting an offer. I haven't even gotten a declined email and it's been several weeks now.
