Impossible to tell. I had one back in March and 30 days after my internal rec i got a "fix it" email. I also posted the same question. The replies I got ranged from 1 month to never ever heard anything again. Had to step back and reevaluate. If it was an internal recommendation then it was an obligatory pull and doesn't mean I scored well enough necessarily to be pulled. What I WISH I had done was had a application review service go over my application prior to having the internal send it in to be pulled. Not sure if having done so would have resulted in an interview...but maybe it would have had I not needed to "fix" something.
I since then have had a service help me get the application tip top.

With that said does anyone know the required time you must wait to have another internal application pull? Is there one? I've heard none, 6 months, and one year.
