INTERVIEWER: What are your salary expectations? CANDIDATE: Before I state my requirements, I would like to know the entire expected compensation package including salary and benefits. If need be I can present my counter.
[0]: One particular company I worked for had an a cap on what percentage raise you could receive, even when changing to completely different positions in different departments. There was as running joke that "the only way to make money here is to leave and come back". Once I left and realized just how horrifically underpaid I was there, I saw no reason to return.
That way they have a number at least... But in this type of situation, the interviewer is expecting to have the upper hand, and they are probably going to act like it.
