Pretty unprofessional, to be honest - and not because there was no job offer. E-mails following up about things that shouldn't have been asked (can't look at past e-mails to confirm what we had previously talked about?). Interviewer led off with a salary question and was very combative about my response (and uninformed). Not a particularly great note to start an interview off, but I tried to not let that affect the rest of the interview. Throughout, the interviewer never really asked about what I knew about the position or Blizzard. Mostly seemed like the interview was to get the lowest paid person filled into the job with little regard to any other aspect of skills or personality.
