Too much credentials
Copa does not Interview nor hire FOs with B737-NG Type Rating. If you are lucky for an interview, they wont hire you anyway.
You are too smart for the position. As soon as you see their operations and mentality, you will split.
FO Non type raters, are usually dumb and egotistical about their first jet. So they end up swallowing all the BS until they have enough Jet time to make it to the big leagues. By that time you have already returned Copa's investment.
Captain recruitment have stopped.
Its as simple as that.
