What do you want to do? I work at an space engineering company after completing my physics degree and I know of quite a few people who have maths degrees. Maths is one of those subjects that you can apply to do anything, but the most money will be in engineering (most interesting) and I guess finanicial stuff (boring)
I have always worked in Engineering. Currently working as an inspector for the insurance company. I think I need a change. The medical applications of Statistics looks intriguing.
