They were proffesional pilots infront of me and you are just a name on the computer.
Looks can be deceiving. Be aware that at PTC none of the instructors have airline experience, they are all general aviation pilots. But the real funny thing is there are at least 3 guys walking around wearing four bars on their shoulders as if they were airline captains - who have less than 250 hours on light aircraft. One guy i believe has no IR or instructors rating, just a cpl with around 150 hours total time, yet he walks around with rank of airline captain at PTC, and i believe he's part of the recruitment team.
It's a scam, PTC are all about marketing, you did the right thing by coming to PPrune and asking people opinion, you cannot trust PTC, they just want your money.
