Star Trek's very first Prime Directive is not to interfere with other civilizations; after all, as Commander Ryker put it, it's not the job of the Enterprise crew to keep the intergalactic peace. However, that doesn't mean there's not plenty of work do with within Starfleet itself, from keeping the ship shipshape to liaising with allies and Federation members to training to security.

While everyone in Starfleet is obviously highly qualified, getting on board the crew means you're the best of the best in your field. So you have to choose the area where you can excel above all. Perhaps you have a knack for understanding people's aches and pains and for healing their ills. Maybe you're more machine-minded and have engineering skills that are second to none. 

Maybe you can easily think in multiple dimensions - three physical ones, plus time and perhaps a few others - meaning that your sense of direction is second to none. Or maybe you are a natural leader of men and women, someone who can bring out the best in everyone around you and ensure that clashes of personality are managed as best they can be. Whatever your particular specialty, there's a role on the Enterprise for you, so let's find out what it is!
