I've been following this thread for a while, so I'll wade in with my GE experience so far:

Applied: 5/25 (midday)
Conditional approval: 6/14 (midnight)
Interview scheduled: 7/5 at JFK

JFK interviews seem to be booked into early August, so I guess I scored a cancellation slot. The Bowling Green site is booked until early October -- but I work one building over from the Customs House, so I might start showing up at different times to try and snag a walk-in interview.
