The Interview process takes place at ACO headquarters in St Louis Missouri, the actual location is about 20 minutes south of the STL airport. Transportation and any costs associated with the interview are at the applicant’s expense. Once you walk in, they have you wait in the lobby area while they look over logbooks etc. Then they call you back and you take a 25-question test that is a random selection of questions from the ATP Gleim. So looking through that book will definitely benefit you. There are 4 or 5 tests but none of the questions consist of calculations and it is all multiple choice. There was a lot of IFR and airport marking questions and just the basic pilot knowledge. They also give you a test that is a personality-based test. You cannot pick any wrong answer so just be honest with the test. There are six scenario based questions and they make you pick two of them that best fit your personality and with that they have can take those two selected answers and come up with an accurate outline of the applicants personality. Once you have completed both tests, two people from ACO one being a Pilot and the other is an H.R representative come in and give you the basic face-to-face interview questions. Along with a few scenario based questions such as (The P.I.C wants to take off illegally what do you do etc.) Then to end the interview he will ask you a few questions that refer solely to the Cessna Caravan to test your knowledge on the aircraft they operate.  They do ask you to bring in 5 letters of recommendation 3 professional and 2 personal however they never even looked at my letters. After the interview has been completed, they leave and go talk amongst themselves and leave you in the conference room waiting as they make their decision.

Also, they first get into contact with you via phone where they tell you about the company and proceed on with a small over the phone interview.
