I applied online and received a call back after 2 days requesting an interview, the interview lasted 15 minutes and I was told I would receive a call within 5 days.

Interview was on-line. Simple, straight forward. Very clear about location and expectations. Working at the Airport adjacent the USPS required additional checks. Essentially, a partime position with the minimal overtime until their version of a "peak" or maximum shipping/receiving. Generally holiday buying surges, whihch are fairly predictable.
