This has been my experience with my last two offers. In the moment, I was just glad to have gotten a job. My current position offered less than 80% my previous hourly wage, but they had told me beforehand they couldn't match my last job, but that I would get more hours (which I do). It came out to about even, and I got a 17% raise after 4 months, so now I'm making more than my last job, taking hours into account. I make around 35k, I'm 22, I've dropped out of 4 colleges/universities, and I'm an IT tech with a couple years experience (small businesses, so higher quality experience than level 1 or something). I had very little power to negotiate anyways, but I was irritated with myself for not rehearsing a "let me think about it" spiel or at least vaguely asking if they could do any better.
