guys i have been with fr for the past 2.5 years, when i did my assessment, i felt they focused a lot on the sim so whatever you guys do go in to a sim and practice even if its jus a fixed base 737. practice steep turns climbing turns descending general handling, raw data etc and use your partner they want to see team work not a hot shot, when you get a non normal its essential you work together, use a problem solving acronym and take your time.
and they don't compare you to other guys at the assesmment, if you meet the standard you'll get it, all the guys that were on the selection day with me got through good luck!!!
