I am currently searching for a job, and one company asks what my pay rates were at previous jobs. I don't remember what my pay was. The jobs were internships, and I was more excited about the opportunity to intern than the exact pay I was receiving. I didn't keep my offer letters from those jobs, which I realize now was a bit of a mistake.
How should I go about finding out how much I was paid by these companies?
One idea I had, and the one I'm currently planning on doing, is: visiting my old employers in person, asking for the HR department, and asking them if they can give me the information I'm looking for (bringing several forms of ID with me, of course). Does that sound reasonable?
