Know your current type. Be prepared for a question on it to see what you know, especially if the interviewer has flown that type before.
Know the operation you’re applying for and the rule set under which is going to operate.
Embrace the “tell me about a time when you….” question. I like these as it tells me about a candidate’s ability to tell a story, communicate, and what they took away from it (lessons learnt etc). Its not really about the event.
