[Harry Potter] Do wizards have to get real-life skills or jobs after going to Hoggwarts or do they just live in the wizard world forever?

Setting up my young kids to play Lego Harry Potter and seeing the the game broken up into Year 1-4 and 5-7 made me realize the kids in Harry Potter spend a shitload of their lives at Hoggwarts. Once they graduate from Wizarding School... then what? Do they go on to become lawyers and doctors and accountants and graphic designers and web developers with their education on alchemy and black magic defense? 

Do they then have to go to Muggle-school for another 15 years and catch up like normal kids and learn actual history and life skills or do they just conjure up Muggle money for their whole lives and live however they want? Or do they just live in the wizard world forever now and do their careers in that world as whatever alchemist or wand-crafter or gryphon-whisperer or something?

I haven't read the books so forgive me if this is a really stupid question answered on page 2.

It is answered in the books. Hogwarts graduates get professions within the wizarding community. 

With some notable exceptions, they essentially live their entire lives in a secret parallel society from Muggles, having little to no interaction with anybody who is not in the magical community.
