I had 2 interviews. The first was face to face. The average interview lasts for 20-30 minutes. My interview lasted 45 minutes. He obviously had a set of questions to ask as to my experience and how I deal with certain situations. I had a good experience and asked him many questions about the company which I think impressed him. The second interview lasted close to 30 minutes. The was very enjoyable and this was more of a personality profile.
