As a low hours pilot they won't expect you to be a hotshot in the 320. Good hand eye coordination, good basic IR flying skills and most importantly they want to see that you can be trained and that you take instruction well. On this point, listen very carefully to any advice or tips the instructors/interviewers give you. Its also important that you learn from your mistakes, eg on your first ILS approach with flap and gear extension you end up getting high due to not anticipating the balloon effect, they will want to see then that on the second approach you have learned from that mistake and anticipate accordingly.
