I never did it but once, as I think even the worst interview on earth is something you use to learn.

But for the one time when it happened, long long time ago, it went like that:

I was sitting at a round table with 4/5 personn in front of me doing the interview, among them the CEO

this CEO in the middle of the interview ask me how much salary I would expect

I don't really block and answer straight away

then the CEO went into a fury on how I would dare to ask that much and that the price of bread could not augment that much

I kindly asked if he was comparing me to some slice of bread ?

He answered "yes"

I stood up, smiled and walked out of the room, not saying a word at all.

Stupid small story, but since that time I will always check the range of salary a company expect to pay for a job offer, it also helps to filter out the company having unreasonable expectations (I'm looking at the one who look for tons of languages, 10+ years of experience and want to pay you the salary of an intern).
