Hey there, I was at ATP Jacksonville during the beginning of 2012. I went down with a private and an instrument rating and about 240-250 hours. I had a custom program built PVT-MEL, COMM-MEL, SE add-on, MEI, CFII, and CFI(SE add-on).

The training I got was for the most part pretty good, but its a real roll of the dice for who you get as an instructor. I lucked out with some real good ones, but its not at all uncommon to get an instructor fresh out of standardization with absolutely no clue about what they're doing.

Also, CFI ground school is a real roll of the dice again, I was extremely fortunate that their asst. chief pilot (S.S.) taught our ground school, and it was one of the best experiences I ever had, but certainly don't count on this (I've heard some real horror stories).

Now....working for ATP as a CFI is a completely different ballgame. If your planning on working for them run as fast as you can. They treat their CFIs (and candidates) like complete sh*t. I went down to work for them after I completed training and it was the largest waste of time, money, and effort I ever made. Spent over a month in the call center answering phones 6 days a week for minimum wage, living in an apartment with 5 other people (shared bedroom). They don't have enough open positions to fulfill their "guaranteed CFI job" lie, so while you are there they will dismiss you at the first possible chance they get. They fired 5 out of 8 of my standardization class after only one flight in a Cessna.

Bottom line, training with ATP is a dice roll (I got lucky). Working for them is an absolute nightmare (assuming you don't get fired first).
