Agreed, and not saying that at all, but to me thats the biggest tip off that its a bad fit. If they're secretive with salary, or try to hard sell me on the position, or they're unwilling to make a decision and be confident in it without many many meetings then those same things are likely to be reflected in day to day situations after coming onboard.

Interviewing should give you a fairly clear picture of how functional or disfuntional an organization is. You just have to be sure that its a function/disfunction mix that you can thrive in.
