Before setting you up for the interview they call and make sure you have the flight time they require. I don't know how much is the minimum but I had 6000+ TT and about 1400 TPIC (2000+ PIC) when I applied. (Civilian - 5000 hrs in an RJ)

So I would assume that getting nixed after the interview would have more to do with how the interview questions were answered. I did an interview prep and it was 1000% worth it.

I kind of regret not applying earlier and I'd be on line with 6 months or a year more seniority so I'd recommend applying early, if you get turned down, no biggie, just apply again. Though I did want to have 1000 TPIC in the logbook, just in case, which is why I waited.
