Don't interview very well, interview with AIG IN THE MORNING SECOND INTERVIEW

The best and most obvious answer to your question is; just be yourself. Try to remain calm, relaxed, speak clearly, make eye contact, have good posture (feet on the floor), dress conservatively, answer questions precisely (don't carry on... ), etc.

And, I would have a question or two planned to ask them to show interest.

I would also try to obtain as much information about the position you are applying for and AIG as possible as this will impress the interviewer, possibly Google.

Good luck, please let us know how you did.
