I interviewed at a place where I knew someone who worked there and knew exactly the number they were looking to hire at, I named that number in my interview and they still tried to undercut me. I said, no I want $original_number in my response email and they caved in literally 5 minutes. Why?!?!? You found someone willing to take the job at exactly the team's budget. Shouldn't you be popping the champagne that it's painless and everyone's happy?
If you can identify a company's inconsistencies in policies or behavior, you can identify different sets of incentives different parts of the company are under.
A few really big companies might have a different attitude, at least for their major players. I know for a fact that these big companies will offer less than $70k to work in silicon valley, which is a slap in the face to a new grad that was getting better offers in low COL areas.
So where are these mythic companies that don't care about money and give all new hires a fortune without trying to control costs at all?
But maybe you consider that to be a part of company culture too. What I’ve noticed though is even fantastic engineering companies might crappy departments for other things.
