I had ~ 17.5K hours, 2 x widebody Boeing types & 3 x widebody/1 x narrowbody Airbus types when I got in. 8 months between applying & getting the Hogan invite.
In my newhire class, there were folks with just over ATP mins. It's a tough nut to crack, and I have no idea what triggers an application review, except attending a 'Meet the Chiefs' event or job fair seems to have an outsize influence on getting the call. Best of luck - it's worth it.
