> everything he described seemed the same or basically the same as every other employer

If 24 hour SLA and employers helpfully following up on what you got wrong in the interview and offering to get on office hours with you so you could retry in six months is "basically the same as every other employer", I have been interviewing at the wrong places for 15 years.

This is, of course, assuming that everything the author says is true. They could be exaggerating. It sounds exhausting to do these office hours as an interviewer in addition to running a company.
