I would definitely get some time in a 737-200 sim. Think it might be a bit too much of a learning curve to learn to handle a jet and the high speeds involved in a 45 min assessment.
When asked at the interview what I'd done to prepare I told them I did some time in a 737-200 FFS to prepare and they didnt seem to mind. You prepare as much as you can for flights, so why not for interview, was the view I took.
I used Realsimulation, 1 hour did the trick, I used MS Flight Sim to brush up on my scan.
All the best of luck.
PS. I know 4 blokes who are flying for Ryanair in the Cadet scheme and all are loving it.
