About 10 years ago, I learned the hard way that the questions you ask can determine whether or not you get a job. I had received an offer at a large company, and when I learned that some amount of on-call time was going to be required, I asked whether this was a 24-7 thing, or whether there was some kind of rotating system of shifts. They rescinded the offer just because I asked the question; I was really glad they did, because I didn't want to work for a manager who would do such a thing. (I ended up taking a different job in the same company, for more money and with no on-call requirement.)
Which brings me to another point: if your questions are reasonable and a company declines to offer you the job just because of that, you probably don't want to work for them anyway.
