Now that I'm somewhat established in my career, I don't think I'd ever accept a job offer without a personal referral-- someone I know well who works at the company and can vouch for its culture. I don't think you can judge a company's culture from an interview; as you say, it's easy for them to be on their best behavior during an interview.

I'm sorry your experience has been so bad-- it's really not that bad everywhere!
