I applied online. The process took 3 days. I interviewed at Colorado Democratic Party (Denver, CO) in July 2014
Interview
They asked online for a cover letter and resume. They contacted me about an initial interview within the day. Then I went through 2-3 phone interviews. Standardized questions off the internet. Very simple process, just talk about what a hard worker you are and that you're willing to learn and all that jazz.
