WITS America Corp. interview questions

Interviewer asked a couple mid-tier questions, but continued to tell me answered incorrectly.. Interviewer scoffed at my current employers agile processes (1-3 month sprint turn-over per project at a software agency). Interviewer then proceed to tell me "I only have 5 more minutes for you" 15 minutes into the interview, during the portion I was asking questions. Very informal, seemingly biased, interview, lots of awkward silences, social nuances and satire.
