I'm filling out an application and they're asking me my employment history. I've never heard a job before but I do have some volunteer experience from high school to college and have been a part of some clubs. The ones I want to out down, I remember the names, but not the numbers and I haven't talked to some of them since I left my high school. Should I just put N/A for every one? They already have my resume with all my volunteer experience and that's how I got an interview.
