No it has not changed the ATP requirement. I was in the group with the new process. We were the first group to go through it. Several guys were sent home because they did not have the ATP written or a current 1st class medical. Get everything that is listed on the interview invitation and you don't have to worry about it. If you come in without anything they will send you packing. Pinnacle is very strict on the paperwork side of things, not as bad as XJET but close.

Edit:
If any of you want to know how the new process goes feel free to PM me.
