I worked over the summer as a student at Toyota, and didn't love it or completely hate it. The hours were long (10 hour nights, 9 hour days), and during that time I had basically no social life. We worked every Saturday on days when I was there, which added to this. Besides the work being generally hard- especially doing it in the time frame needed-, and the pain it causes (general aches, nothing too bad), it wasn't the worst job ever. The people I worked with were nice, and the days mostly went by relatively fast.
Benefits after 3 months, days off, decent pay
Long hours, hard work
