I have a couple of questions I tend to ask. One of them is
do you have a dresscode? If they have, it's quite unlikely I take the job. The other is,
where was your company 10 years ago, where is it now, and where will it be 10 years from now? And it's not so much that it matters to me where they company will be 10 years from now, but how much of an idea the company has (and, most important, how much is communicated from the boardroom to the level of the people interviewing me).
But the one about over-time is a good one to remember. As for project plans, I've worked in enough places where they didn't have project plans, and were still nice to work at - and vice versa. As for the monster - last time I left a resume there was in early 2002. Recruters are still calling because of it.
