Nighty,
I was told yesterday that the test is A/C handling oriented (for those who have never been in the 737).
The pilot I met and who did it at DUB had to:
SID then, perform vertical S's manoeuvres followed by snap entry into a hold followed by an engine out ILS RAW data (x-wind). The instructor was a contract (apparently) and not CityJet TRI/E. That's what I've been told.
Candidates arrived in mass but were not allowed to talk to each other after sim exit and showed the door...
Be prepared if you don't know the 737 sim, it looks a little bit hard to make a good show.
