MathWorks interview questions

I submitted my resume through mathworks website. A few days latter, I got a phone call from HR, all questions were behavioral, and they told me about the company, the position, the freedom to choose the project to work on .. etc. This one was REALLY easy, then scheduled a technical phone interview for the next week. The technical interview was going very fast, lots of questions that the interviewer wanted to ask in a short amount of time (about 40 minutes), questions in linear algebra (vectors, matrices), lots of questions in programming concepts, few Matlab, basic signal processing questions.
