At the interview with the C-130 unit I got hired with, here are some things they mentioned...
- You'll need to fly MUCH MORE than just during drill weekend. You need to stay not only current, but proficient.
- You will have a laundry list of quals you'll have to keep up with and depending on the airframe, you could have a ton (fighters, I'm sure do, as does the Herk) or not nearly as many (KC-135)
- At the beginning (first 3 months or so), you'll pretty much be expected to be there all the time getting a lot of flying and experience so you can go on some "trips"
- After you're "in" and been around, you still should come in and fly 3-4 times per month. That should be enough to stay proficient and not have a ton of quals to finish up all at once and have to start bumping others just to make your deadlines.
Anyone who's actually a pilot can feel free to debunk everything I typed. I won't take it personally.
