I agree with Cliff...wait till you meet the 2500/1000 mins.
However, being competitive vs meeting the minimum requirements are two different things. An ATP is an absolute must-have on the application.
And the internal recommendation is also helpful...there was some data sent by someone in Atlas HR that gave some numbers of those with and those without internal recommendation. I will have to find the email and post the info when/if I find it.
BTW, the application is FREE...so, apply as soon as you have the minimum requirements met.
Good luck.
