First junior software dev job, asked what I wanted for hourly pay, replied “I need at least $13/hour to survive.” (This is in US, 2007, I was almost done with Bachelor in CS, single mom with two little kids, was also in the army national guard at the time)

I grew up poor, and was very ignorant about salary negotiations. So of course they offered $13/hour. I accepted, thinking it must be fair, and was glad to be making more than minimum wage. Six months in, I’m doing the same work as their devs with 2-4 years experience, find out they are billing clients $100/hour for my work. Then, to top it off, the COO makes a joke in a meeting about how it’s not a big deal for their “technical assistant” to be doing lackey work because he’s only paid $13. Fuuuuuuuuck. That comment still makes my blood boil.

I had a nice manager at the time that explained how salary negotiations worked, but I still think it’s lame as hell. I ended up getting put on salary, $50k/year, after threatening to leave.
