Below is a link to the public section of the Republic pilot forum. That is probably your best source of hiring information, as input will be coming from current company pilots.

The best advice I have is don't get too worked up or frustrated during the sim evaluation. It is pretty unstable and the instructor's standards are set accordingly. Ultimately, just be yourself and remember that they want to hire you. If you haven't seen the study guide or gouges, make it known here and someone will direct you to them.
