MathWorks EDG interview questions

I had a friend working in Mathworks before so he referred me to his colleague. Then I got a phone interview in Nov, 2019. They asked some basic question about C++. But I did not hear anything back after that. Then I applied the summer internship for summer 2020. I just submitted the interview video online and then they are sending me the code challenge. Need to finish in one week.

There was one technical interview and two behavioral interviews. The technical interview consisted of a data science problem from hackerrank and a coding problem. The two behavioural interviews were standard questions.
