I'm a line pilot, so not familiar with recruiting or training. But if you're worried about not being current enough, I would be willing to bet they'd be willing to front you some bonus money to get a plane + instructor and/or some frasca/redbird time to really work on some instrument procedures to show up feeling confident and ready. They're throwing money at helo guys to get ratings, I've heard if them paying some hours towards time building, and 10 hours in a 172 subtracted from your first bonus is way cheaper than a couple extra sims.

Not sure if they have a formal program for this, however.
