For the screening here: the atpl test is pretty basic, mostly perfomance questions, no big deal.
For the sim, as NTR, expect to start at the thr, quick briefing, take-off, vectors to ILS Z RWY34, hand flown but with fd, they give you time for a very quick briefing during the vectors. Reposition at thr, take off and visual traffic pattern for rwy34 (traffic is done to the right). Reposition again for take off, eng out at v1, rotate, ask for ecam actions (the pm will do that quickly or just inform you that it's completed), vectors again, you can transfer controls and do a quick briefing again, intercept ILS 34, hand flown without FD but bird is available, single engine go around at minimums, ap will become available and they will give you vectors to intercept VOR Rwy34, you can use track/fpa to make things easier, single engine landing.
They won't give you any feedback, but you will receive an email about 1 hour later giving you the results.
Honestly, the sim is quite ok, but I recommend you to do a sim session (dont need to be a full motion sim) back at home. They don't want any airbus standard but CRM and flying skills.
