i have always wondered what mathematicians do after they graduate? do they look for jobs? if so, what kind? who they work for? what sector? what industry?

also, i am comp sci fresh grad, now looking for a job.. I did internship and few months of fulltime, i am thinking this is not for me. I dont want to sit on the chair, look at screen, type on keyboard, for 8 hours. Then go back home, debug some code to meet deadlines. Next still thinking on what went wrong and how to improve it, on the bed. I am thinking I just want to be a parking attendant or security guard. What should I do anons?
