Applied online through Mathworks website. * After a week or so. did the first round (HR round) with the questions already mentioned. * After about 1.5 weeks, mail to schedule a phone interview. Just got done with the phone interview. (signal processing/C/Matlab) Answered all questions (3 or 4 of them vaguely). On a personal note, I think I did really well. Not sure what they were expecting for "support engineer" but memorize what all you can. There were a couple of questions not mentioned on glassdoor, I will update others in a while. Left Inverse / Right Inverse matrices How to pass a char by reference in C language Function to convert a string into uppercase - how do you pass the string (value or reference) - my preference Break and continue in a for loop in C How to work on the same figure in matlab after you close and open the application .
