I think a lot of companies forget that the interview is the applicant selling themselves to the interviewer and *the company selling itself to the applicant". That's a strong "reject" signal to me.

But also some of these examples could be from companies who understand the bidirectional dynamic. E.g. if you consider wearing a suit to be a bad sign the company might just as well be glad you don't want to work at a place like that. Win-win!

My contribution to the argument: people who use vapid business buzzwords/ like "win-win" except in the rare cases where it really is appropriate.
