Following an on-campus interview, I was contacted by HR staff at Air Products to arrange an on-site interview. Air Products allowed a reasonable window for setting up the on-site. I was asked to give a 45 minute technical seminar, followed by about 15 minutes of questions - pretty typical for PhD interviews. The seminar was very well attended and the questions were good - a sign that the right people were in the room and that good communication was occurring within the company. The seminar was followed by 5 interviews with technical or group leads in various areas of Air Products. Lunch was on-site in the cafeteria with a current CDP participant. Lunch was low-key and a good chance to catch a bit of "rest". I found the interviews to be pretty straightforward. Some interviewers hit technical topics, but I never felt grilled. I did feel that I had a reasonable opportunity to highlight the technical areas I wanted highlighted. There were plenty of opportunities to talk about past experience and thesis-related information.
