I was interviewing at a place for a DBA position, where the co-founder (CTO) of this company which had raised 100 million plus and about 150 people, was still updating prod on the fly. I told him straight up in the interview, that the first day am hired I would revoke his permission, he said I could not do that. The guy was too cocky, I did not get the job, they burnt through all the cash in a year, and out of business right after! You see the writing on the wall sometimes in the few hours you spend at the place.
