I was offered a job there back in june and did some research. seems like most people i talked to said that it was the sim portion of initial training and more specifically the lack of the trainees instrument scan. i've also heard that they expect you to know ndb approaches and if you don't (planes i learned on didnt have adf) they wont teach you or hold your hand and just flunk you since there is always an abundance of applicants. This is just what I've heard on the forums and may not be the whole story. im sure there are other factors but i've heard this is the main problem
