JB did a phone pre-screen for a while back in 03-04 I believe. After enough guys said "no...its his brother...but I'll have HIM call you back..." they finally realized trying to do screening over the phone on an impromtu basis wasn't a good plan.

That said--anytime the phone is off the reciever its an interview. So is the van ride to the hotel...and the check in....and the dinner in the hotel the night prior. Be on first date ROE and you should be fine.
