MathWorks EDG interview questions

Like all the posts you must have seen so far, the first round for EDG was an HR video interview round. Give an example how you tackled with multiple responsibilities? What language do you think makes you qualified for this position? Talk about a project of yours and what did you learn from the experience? Gpa? Visa status? The second round was hackerank where we had to solve few coding challenges . Options (C and C++ or Java, Matlab or Python) . First few questions were math or basic math questions , then Matlab questions and then C/C++. Awaiting for my third challenge ^_^
