Some of them maybe, but asking the working hours, the health insurance, and whether the company will wait or buy out the two months might be complete deal-breakers, and saves both sides time by asking up front (and for the first two, should have been offered up front prior to the interview, to prevent wasted time).

It’s like being offended if, on a first date, one person asks if the other ever wants to have kids. If you know the long term potential is dependent on something, getting that question out there up front saves both parties, and anybody getting upset over it is scamming (getting them invested before being willing to discuss it). Same as not talking about general (not specific) payscale for the position, medical coverage, hours, or whatever until the second or third interview.
