[Harry Potter] Hey I just graduated from Hogwarts, I now need to find a job.

I was part of Slytherin House at Hogwarts School of Witchcraft and Wizardry. I graduated recently, and although I wasn't top of my class or a prefect, I wanted to to get a decent job. 

I was good at Charms and Transfiguration for my core classes. I had Divination as my first elective, but I wasn't too good at it. For my second, I had Care of Magical Creatures. During, my last year I was able to take Apparition, so I guess I was lucky?

However, now I need to find a job...what do you guys recommend? I'm sorta thinking about doing something in security, but I want to hear my best options.

The ministry is your best bet, if not that then finding some way to get into another government related job (education is big, or law enforcement). If you'd rather opt for private employment, then look to the creative arts (book writing, performance, design, etc) or selling a specific magical skill. 

You can advertise your business in most magical media.
