I applied online. The process took 2 days. I interviewed at US Postal Service (Nashua, NH) in Nov 2013
Interview
The "interview" was the interviewer looking over my application, asking me if I wanted the job, when I wanted to start, and if I could fill out more paperwork. Easiest interview I've ever had, which seems reasonable for a holiday job and reduced my stress about the application process. Was in the same process with many other people, but all interaction was 1-on-1.
