Applied - 1/17
Conditionally Approved - 1/26
Interview - 1/27 (I got lucky with a cancellation at an airport I was transiting through the following day)
Approved - 1/27 (received email 5 minutes after interview)

I definitely recommend checking random airports for cancellations - the soonest appointment within 2 hours of me was going to be ~2-3 months out.
