Back in the day XJT had one of the easier 121 interviews as well and they weren't considered to be hiring lesser applicants. I doesn't really matter in the end anyways, my opinion is most guys can get through an interview with a couple weeks of gouge study but most idiots will get filtered out during training. Again don't worry about all of the other stuff, both companies will provide quick upgrades so go where you think you will be happiest as that is all that matters. You seem to want to go to Compass so go there (assuming you pass the interview).
