Was through a recruiter. Gave me 24 hour notice to do a technical presentation. I threw something together and thought I did OK, although what I presented wasn't close to what they were looking for (I could have done a more targeted presentation with more notice). The group was friendly, although they didn't give me details on what they were looking for - I wasn't sure if they wanted a course developper or a trainer - I am the latter. I keep seeing postings on job boards for both types from this company. I never heard back on the interview, but given what I've seen that's probably for the best - I'm not sure they know what they want.
