I interviewed with colgan last week. They flew me up and back the same day as the interview. They pick you up at dulles, and drive you to the headquarters. Interview was 10 minutes long. Me, and 2 of their pilots. Asked same questions as on the aviation interviews website. Also a mental math..time speed distance question. You will probabaly be relocated to maine. They offered me a class date via email the same day as the interview, after telling us we would know in 1-2 weeks. They have no union. Upgrade is when you have 2500TT, 700 in type. They interview 8-10 a week, and have a class of around 10 once a month.
