MathWorks Applications Support Engineer Interview interview questions

I applied through college or university. The process took 5 Days. I interviewed at MathWorks based in Natick, MA .First interview with an HR representative, during which behavioral questions were asked. A Hacker Rank challenge was to be completed before the second interview, which dealt with technical questions.

This is a video interview and the questions are already posted online. This interview did not relate to any professional skills. And I just answered question before the screen. No one communicated with me.
