[Star Wars] Say I'm regular guy who want to be an X-wing fighter in the rebellion. How do I get there?

*Either Canon/Legends is fine.*

I'm a galactic citizen, who saw through the Empire's propaganda and decided to join up with the rebellion. I know a guy how knows a Sullustan who knows a guy to get me in contact with the Rebels.

I want to be a pilot. I'm reasonably well educated. Not really a top expensive education, like those spoiled Moff's brats get, but I got a decent basic schooling. 

How do I go about becoming a pilot? Can I get an flight education in the rebellion, or should I prepare myself in an other way? Will I get training missions before flying into a swarm of TIE-fighters, or is it more of a "natural selection".

I've heard that even moisture farmers with zero spaceflight hours get a crack at it in a cockpit and I figure I can do that as well.

Fighter pilot is one of the most desired, and most difficult, jobs in any military.

A state-supported military, like the one fielded by the Empire, can be very selective about who they put in a cockpit, because they have an abundance of volunteers. In fact, the Empire has so many people volunteering for their military that you'd almost think they were being forced at gunpoint. And these volunteers are so excited about their mission that they're willing to go into battle without shield generators, because that sissy-boy "protection" would just slow them down.

The Rebellion has to be more careful. Both X-Wings and pilots are hard to come by, and represent a massive expense for the poorly-funded, rag-tag bunch of rebels.

Anyone can apply to be a fighter pilot, sure, but expect to demonstrate your skills before they toss you in the driver's seat of a multi-million credit war machine. This can involve flying through simulations, completing training missions, or having experience flying your own vehicle in combat. Of course, this can be sidestepped if you have a Princess to vouch for your abilities.

Once you're selected for the squad, you're put under the command of the Lead wingman, who will see to your training. You'll be assigned an X-Wing and an astromech, unless you happened to pick one up on a desert planet or something, and you'll have to train regularly to keep your skills sharp.

But don't worry. The targeting computers do most of the hard work. It's not like you can just switch that off or anything ...
