What was your first job before or after uni. Mine was an electrician working for my dad.
How about during.
While 14-15, I worked at a bike shop building and repairing bicycles. Left when the family moved across town and I changed schools.
While 15-16, worked at a gardening center on weekends, after school, and during summer. Left for a summer science program at Colorado School of Mines.
While 16-17, worked as a stock person in a grocery store (Kroger). Left when I started university. Used earnings from jobs to pay tuition, books and most of room and board.
At 18, full-time summer job as a plumber's helper and maintenance person, working on plumbing, steam and condensate lines, sewer lines, A/C and air handling systems, pumps, motors, compressors, . . . Worked part-time during university ~20 hrs/wk doing maintenance, and also got a job in the food service, which paid room and board at university.
At 19, full-time summer job at an oil refinery in the compound and packaging department. Filled containers with various oils and transmission fluid. Unloaded trailers and box-cars during the summer. Worked part-time as a night-time janitor.
At 20, changed university, and for four years (20-24), took summer jobs as an iron worker. It was like building a giant erector set. The best part was walking out on a 6 or 8 inch flange of iron to unhook the crane (sometimes in the wind), then carrying the iron purlins out to fasten the rafter. One learns not to worry about the distance to the ground.
Starting in grad school, I had research (part-time) and/or teaching assistantships. Took a full time job (while doing MS program) with the local municipal water department as a station operator responsible for the entire city water system during evening or graveyard shifts. Gave up the job after starting a PhD program - I really needed to have time to sleep.
Left grad school debt-free.
First professional (salaried) job was as a consultant in the nuclear industry. The various jobs as well as my education really prepared me well for a professional career.
