Very friendly and make you feel at ease. First is always the standard question " Tell me about yourself" , then they asked more about my past experience as it was based on Oil and Gas industry. Infact I was working on Engineering side of the same Project for which they did procurement, so most of the other questions evolved around the same. After interview, they asked me to email what are my expectations when I will start working as an Intern here and next week I got a confirmation letter!
