The position was posted on idealist.org and I just emailed my resume and cover letter. I was contacted a few days later for an interview. I sat down with two associates (my superiors) in the communications department. They asked the standard set of questions about my background and previous work experiences. They didn't ask any difficult or tricky questions, which partly made me wonder how hard it would be to get a job there, since it seems like you would want to see how candidates can handle tough questions. I didn't even have to answer any questions about my knowledge of the field. The office overall seemed pretty relaxed and casual.
