Oasis Alignment Services interview questions

Phone interview with HR went wonderfully. Based on questions and some personality profiling, I was a great match for this position. The 1:1 was a different animal. Interviewer was extremely difficult to 'read'. I consistently got the impression that he was 'fishing' for some specific set of answers. Lengthy, but not particularly productive, and I left with very little confidence the process would move forward. I was interviewing too, and not convinced I could work for this manager (interviewer).
