COMSOL Application-Engineer interview questions

I was recruited for the role and invited to a telephone interview. The experience was negative as I thought the questions were quite difficult. The interviewer was quite hard to talk to and advice would be to only apply for the role if you are an expert in FEA, as I am a recent graduate and felt they were looking for someone with a lot more experience despite their job notice.

3 part interview. Part 1: phone interview about flow and simulation topics. Part 2: phone interview combined with white-board exercises about flow and simulation topics. Part 3: presentation exercise and tutorial demonstration.
