know your basic Ifr stuff ....if you can figure out the hold entry without taking 10 minutes and having to draw out diagrams I think it would be a bonus . brief the hold,approach and have good communication with the PNF.Remember the holding procedure includes slowing down to holding speed ,advising atc upon entering the hold as well as reading back the holding instructions. Use positive exchange of controls!!! Make him work for you he will and he will be a very personable guy who will make you feel comfortable.If your approach sucks be proactive and go missed ...The approach should be a stabilized one .Be prepared that you may have to fly raw data . Dont count on having the flight director because some do not get the flight director .I did not have it. On the approach in 121 many airlines have altitude callouts when on the approach .This is the time to make a good impression .

Most important ... Be someone that a captain can spend days with in the flight deck . Leave the cockiness at home.... better yet if you are cocky its time to humble yourself .Good luck on your interview and sim !
