In order to pass IOE as a DEC, you must pass a line check and Fed Ride. They are looking for people who act like a captain, exhibit sound judgment, who make their altitude and speed restrictions, and don’t bust any FARs or aircraft limitations. Even an FO can fail IOE if no line check airman will sign them off after lots of extra IOE time. It is not common to be let go after IOE, but there is more to being a good line pilot than the ability to pass a checkride.

All new captains at Envoy are required to get 50 hours of IOE, FOs get 25 hours of IOE. They will give you more if needed, but eventually someone is going to make a judgement call on you.
