I did a summer job at UPS during college. I processed packages going Canada->U.S., checking that the waybills were completed correctly, etc. Night shifts, 8pm-4am IIRC, all summer long. Tedious as hell but I had some cool coworkers at least.
After I graduated, I did some shitty sales jobs (call centre, door to door) for a bit to pay the bills while I focused on music. But then I settled into a job with an office services company for the next few years. Started on a night shift working on a digitization project at an financial firm. Night after night of scanning and QCing boxes upon boxes of their customers' records. Then I moved to a day shift at a corporate office as team lead of the mailroom / print room. Pay wasn't great but that was such a fun job. We did a bit of everything there.
Then 8 years doing volunteer work on education development projects in Vietnam.
Moved back to Canada in 2016 and got a job doing outside sales. Not exactly what I had hoped for, but overall it's a pretty good gig.
