MathWorks Application Support Engineer Intern interview questions

I talked to the representative at the university career fair and got a phone call from HR 2 weeks after. I was asked a few behaviaral questions and was scheduled a technical interview in one week. The technical interview mainly consists of basic math, control theory, programming and MATLAB. The question is not hard but very detailed. I forgot some of the basic stuff in C and control theory. The whole process went well and the interviewer was nice.
