My "loop" was done by people who spend an hour with me asking my questions designed to see if I fit into these "principles". After the third interview, I was exhausted by parroting the same damn story multiple times - I mean, how many stories can you come up with?
The bar-raiser was changed at the last minute and I got some random dude on the phone who clearly had no idea what the job was about. He spent his hour interrupting me and peppering me with random questions. I've been a lawyer and am used to this so it was not an issue, but it was an all around weird, cult-like experience.
I did well enough to get an offer, but when I walked out of the interview I'd called up my wife and told her I would never join a company that seems to be more cult and less company.
The whole vibe was just super weird. I mean, I'm used to big tech companies thinking that they are doing world changing work (Msft, Goog. Never interviewed with FB), but this was entirely on a different scale.
