I applied online. I interviewed at No Starch Press (San Francisco, CA).
Was emailed to schedule a phone screening where I had to answer basic questions about how I knew about the company and why I was interested in them; came in for an interview and answered longer but still standard questions about my skills, work history, how I'd handle customers, what kind of environment I like to work in, etc. Second interview included meeting with everyone who worked in the office at once, basic computer skills tests, as well as some random testing and questions from the founder. Overall the process took several hours. They also called my references.
