For me the process took about 2 months, from my understanding this is a relatively short timeframe. After applying you go through a few test, drug, background. Then there's the interview and training which was about a month long in total.
The process took 3 weeks. I interviewed at US Postal Service
Interview
Group interview then one on one. Group consisted of about 30 people, about 10 people out of that group were hired. I was offered job at the interview. Was informed Job would be limited to 6 weeks, starting shortly before thanksgiving and staying through the first week of January.
I applied online. The process took 3 weeks. I interviewed at US Postal Service (City of Industry, CA)
Interview
Simple questions and alot of paperwork took 4 hours. 2 weeks later they will send you goto get a drug test. Then that takes another weeks or less. After that orientation for 2 to 5 days depends on the position you applied for.
