PayPal interview questions

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.

I was first interviewed by the recruiter, who is friendly and easy to communicate. She got back to me in timely manner with a phone interview arrangement with the hiring manager. However the interview with the hiring manager wasn't a professional experience. First, I she was absent and had a peer in her team to interview me with no advanced notice to me and to the recruiter. Second, the substitute interviewer wasn't prepared and no focus questions. She called the conversation off without giving me sufficient response time because she got to run for a meeting.
