3 hour interview did not feel like it went on that long. Relaxed and informal I did not feel like I was in an interview. Talked through my CV was asked questions throughout but never felt interrupted or being questioned was a natural 2 way conversation about my past careers evolving into more detailed questions about my experience. Approach to various situations and technologies I had used. This was followed by a whiteboard exercise 20 mins of looking at a description of a system then talking through how I would test it, this was again a 2 way conversation with the interviewer expanding on points I made giving there own view on items and even coaching on the Sorenson process.
