If you join Gojet as DEC, what will happen is...
... What will happen is.... Drumroll....
You'll go in all bedazzled and amazed at how laid back it is... You'll study your limitations, your systems and your sop. Then the examiner will ask something totally different, be offended that you didn't study it, and ask you to elaborate on something you never even heard of. Probably thread wear in winter operations or terps parameters for an airport Gojet used to fly out of five years ago.
You will be told you did okay on the oral, but let's mark it unsat so you can go review a few more SOP pages and you'll talk about them with another examiner the next day. It's for safety, to help you grow, to make sure you'll have a better grasp of things.
You get to the simulator, and everything goes great. You're using resources and managing your speed. Then the sim will freeze suddenly during a single engine go-around, the examiner will be all red in the face and ask you to look at your airspeed. It's 15 knots higher than V2, and you're a few degree off your heading too. So you're told you did a great job, but let's try that maneuver again next week.
Congratulations, you just added a decade of self inflicted hiring ban at any major airline. You're now in a deep ditch, a muddy hole, and you have to spend the greatest hiring cycle in aviation history proving you've learned your lesson and improved yourself before you can move on. The training failure voids your flows, and limits your journey onwards.
Gojet, or any regional for that matter, have extremely marginal training programs, but the KV standards for Captain are much higher than for First officer. You cannot expect Gojet examiners to let anything slide just because you entered as a street Captain. Entire classes - everyone - have failed. DEC failure rate is very high, although many resign before attempting the checkride when they realize the instructors (who are Flight Safety contractors who've never flown a Gojet airplane) didn't teach them properly. Gojet examiners, Flight Safety teachers. A lot gets missed by the ground school instructors.
