I interviewed at The Air-Conditioning, Heating, and Refrigeration Institute
Interview
There's no phone interview, just one round on-site interview. The leader was very nice and he asked just normal interview questions. In the last 15 minutes, I was asked to complete 15 problems by hand, which are normal math and stat problems.
