MathWorks Software Quality Engineer interview questions

There are three round phone interviews. If you pass, then you can meet the team onsite. Unfortunately, I didn't. The first round is from the Hire Manager, the questions focus on C++ and Matlab. And the second round is online coding. The last round is some open questions about their product. To prepare the first two rounds, I suggest: a) read the interviews question for Associate Support Engineers; b) download a Matlab User Manual to read it - only 100+ pages; c) if you have no time to do the previous two, make sure you know what 's cell and what's struct, as well how to convert the one to the other. No idea to answer those open questions.
