All the recruiters I have met have no affiliations with TSA or GoJet. Also, we have people at this airline that used to work for TSA. Honestly I don't think that ANY of our recruiters would hold that against you.
What they are looking for mostly is...
1-you can pass the tests which mean you most likely came very well prepared for the interview.
2-how you have applied yourself in the past with regards to college and work. (this is kind of where your college GPA comes into play)
3-the rest of the interview is mostly situational-based questions. What would you do in this scenario? Etc...

I would say that for former 121 pilots right now... if you go to the intreview and pass the tests, and it also shows during the HR interview (as well as the rest of the time you are in the building) that you genuinely want to be a pilot for compass and are excited about it..you will get the job no problem. You don't have to have a perfect answer for every question, they just want to see that you think logically and are excited about compass(ie...not taking the job at compass only out of necessity)

Good luck in your decision. About 90-95 percent of current compass pilots were in a very similar situation as yourself, asking some of the same questions.
