There is no specific written exam paper. You normally have a HR interview with the usual questions, nothing too nasty. Then you go into a different room with (in my case) a base Captain and have a technical conversation more than straight questions and answers. Some specific questions on the A320 if you are typed, and then general Jar procedural questions, dimensions of protected area, When does RVSM start, when can you renew your type etc. Normally quite relaxed. Then a bit of a conversation on life as a pilot in BBU, KTW, etc.
No specific Sim check if you have a type A320, but you do have to do a full LPC before starting your line training.
Hope this is of some help.
