I've found either they tell you up front, or you have to go through the entire process and then at the end they fit you into their predefined bands and give you an offer somewhere in the middle of the band. The bands are not always about how well you interviewed, but can be about how good a story you make based on your previous experience (which probably won't be verified, so go for gold).

> Since more offers is more leverage

Also my experience. You get a number of offers, then go back to the company you like best and tell them what the market is paying.

Either they like you and will bump it up, or they're indifferent and will hold.
