Everybody is hiring so it really depends on where you want to live.

As stated the companies with top contracts AND low upgrade times right now are XJT, SKW & Republic. Eagle's work rules are good and their upgrade time could be coming down significantly

You'll probably need to go to a group interview to get a call for SKW. XJT just takes a little time to process your application, I got a call after four weeks. I'm not sure of the timeline with Republic but I don't think you need an internal rec but I'm sure it would speed things up. I'm not sure about the process with Eagle

Get your stuff out there and then make your choice
