Brie keep your chin up and stay positive.
My only advice is if you have a sim check, get out there and get a couple of hours in an appropriate sim. If you are none TR then they will not be interested in your ability to know the 737, A320 etc I guess they look at the overall picture and your ability to learn.
If and when I move on from my current employer, I will do the same and hire a sim and I am fortunate enough to fly the 737 everyday!
You have worked so hard to just get that sim check, yes its more money, but getting into a sim beforehand is going to help so much.
