Don't know much about their interview process but I've heard from one of their A&Ps that they're really hurting for instructors and that they're getting new aircraft on Monday as part of Piper's Aviation Career Alliance with F.I.T.
I live in Melbourne and have visited their facilities many times since they host FAASTeam seminars there all the time . . . looks like a good professional outfit. I've thinking about applying for their CFI positions for a while now but just can't quite come to terms with the fact that my salary would be cut in half from what I'm currently making in the IT field . . . one of these days I might just take the plunge though.
PM me if you need any insights on QOL here . . . I've lived pretty much all over the FL east coast and overall I'm very happy living in the Space Coast area so far!
