To Labrat's point:
One of my last job interviews I was actually point-blank asked if I was planning on leaving the company in the future because I might get pregnant. My jaw about dropped. And regardless that it is an illegal question to ask; you still have to answer the question with good grace or you "fail" the interview anyway. I didn't get a call back to the company even though I was more than qualified. Needless to say I didn't do more than send the obligatory thank you letter with that company.

I just went a whole round of interviews and was amazed at what people asked about and got away with asking!
