Sim Assessment
The sim assessment is in DXB, first you do a visual pattern of off 12L with A/T, A/P and F/D switched off. Then you do a low vis T/O off of 12L with a V1 cut. Clean up, run the checklists and then you proceed to Sharja VOR. They give you the A/P after you've cleaned up and are level at 3000ft. Direct Sharja VOR and then intercept a radial and track outbound. After that you get Vectors to the ILS 12L. Once you're getting close to the localizer the A/P comes off and you shoot a single engine ILS. At DH you miss and that's it. If that has changed, then someone please correct me.
I'm sure you can find more detailed info here on pprune somewhere.
As for the referees, I would be upfront with them. They understand that some employers can be real jerks.
I understand that the referees are being contacted if they're reasonably sure to hire you, although it is not a guarantee.
