Sure you know the answer to that last question yourself but the main thing they wanna see is that you can learn and improve on your first attempt. I know of a guy who crashed the sim during an interview but made a significant improvement the second time. The airline was satisfied and he got the job so it just goes to show......
Appreciating the extra speed when intercepting the localiser, for example, is something which having flown light pistons you'll probably have to think hardest about. The inertia can be quite a challenge to deal with and the instant thrust you're used to in pistons is not there on jets so basicaly it's an all round proactive, thinking ahead approach which you will have experienced from IR flying, only doubled due to the handling characteristics. Sims in general tend to be far more sensitive than the real aircraft yet this is something you have to factor in nonetheless.
Does this help much? No.
