MathWorks Engineer In EDG interview questions

I was initially contacted by the HR for basic questions which are similar to the questions posted by others. This is just a heads up before the first technical interview. The technical phone interview covers three topics majorly. 1. Mathematics - eigen vectors, matrices, determinants etc. (everything as described in previous posts) 2. Coding (any 2 languages) - C/C++, python, java, matlab. This includes finding outputs and errors from the given code snippets. 3. Theory questions from a topic you are most comfortable with - DSP, Embedded systems and Control systems. The code snippets were really messed up as the interviewer just copy paste in a small window screen. It becomes difficult to read the code by scrolling in the small window.
