Hope this helps.........
* Have they moved the interviews from Cairo to Dubai?
SFS always interviewed in Dubai due to the simulator location. The airline interviews in Cairo.
* Do they do interviews and sim evaluation during the 2 day interview session?
Yep, written test, interview, followed by sim ride in B737 or Hawker 800
* Where does SV do the training for the H400XP's?
Ideally Wichita, but also UK if crews cant get USA visas.
* When do they expect delivery of the next few H400's?
2 in Jeddah, 4 will be delivered by end of August
* Do SV crews ferry the new deliveries across the pond all the way to Jeddah?
Nope, they will get them in the UK.
* Fleet allocation H400 or F900 is "negotiated" during the interview?
Yep, i would even say that the F7X seats can also be negotiated,

* Could you enlighten me about the possible change in the 6 continious days off every month?
No intention to change it at this time, unless dictated by operational requirements. Its a different operation to the line so its not governed by the new crewing system. But ask at interview so you have official response
Just a hint, study the FAA AIM and make sure that you can validate your hours, get some stamp in your logbook, either from your ex-employer or whatever, but HAVE SOMETHING!!!
Good Luck
