MathWorks Software Quality Engineer interview questions

1. Sent email to arrange phone interview. Phone interview around 1hr for general information and tech questions. Half-half. It's kinda surprising that they asked you to solve tech question, instead of "do you know xxx", in the 1st phone call. 2. Full day onsite interview. 1 hr presentation about your education and experience. Five 1-on-1 interviews afterwards including lunch. Four of them are tech person asking relative tech questions, one is HR person advertising the benefit of being hired by the company. 3. They called and move on to background/reference check on the next day. Got offer after a week.
