COMSOL interview questions

I applied online, had 1 phone interview after a month passed. 2 people were on the line during the phone interview- the hiring manager and the design leader. The interview was far more detailed than an average phone screening. I had no idea that there would be 2 people on the line and I was not prepared for that. I heard nothing from the hiring manager after the phone interview.

Applied online. After months got email from a manager asking for a phone interview. The phone call lasted for half hour and was all about personal background. Onsite happened a month later. Two presentations were asked to prepare. One is your own work (anything) and the other one is presenting a model using COMSOL. Everyone is friendly, great location. Got a phone call about three weeks later
