Biz,
Depending on your TT, there are better choices. If you have 600 - 800TT, you can go to other places than Mesa. I don't recommend Mesa, however, it is a great place to build time and they will hire you in a flash. The vast majority of people go to Mesa simply to build up time and get some experience. After a year, maybe two, they leave and go to better places. I talk to a captain at Mesa quite often and he said 85 pilots quit last month. Thats a lot! Good for you because they need pilots ASAP.
