bec beaty,
I am sure if you are going for main crew it will be a similar interview. If you have got previous experience as crew you might be able to apply for 'crew talent' which is the same as crew but a 'manager in the making' and then they might want you to show that you have those qualities in the interview too.
Don't worry I am sure that if you passed the interview the first time you will sale through this time. As you are in the hold pool it may not be the full interview it may be a more relaxed chat to check you are still commited and haven't died your hair purple etc. !!!!
Good luck
