Well, if you make it past the TBNT email bucket, you'll likely get a call in a month or less to schedule you for testing/interview which both will happen on the same day. From there it goes silent for about a month to two months. At that point you may get a call with a position or it could be a call for encouragement on not to give up and try again. Here's the kicker, sometimes you wont just hear anything and other times you wont get TBNT email until months later after applying or interviewing. After job offer, you go through the background/fingerprint process which will take about another month before you get another call or email on start date of the class.
They could always change things up but its how it's been done the last two years. Good luck.
