Do you go through the whole process? I never know if I should just bow out in the middle if I they've scared me off. Just say I think I can save us both our afternoon.

The alternative is to try to keep up the pretense and I'm terrible at that, so I end up sandbagging the interview and then they of course don't make an offer. And no matter how many times I look at it, I can't decide which is less likely to cause me problems in the long term.

I think it's important to go into an interview with the mindset that I am interviewing them as well as they are interviewing me. Why give them a reason for withdrawing an application if they don't ask for one? If they ask for a reason, it starts to become a negotiation.
