I applied online. The process took 2 weeks. I interviewed at MathWorks in Nov 2023
Interview
Two stage testing process which was automated: the first part was generally what I would describe as math or logical puzzle solving and the second part was code focused. There was the option to complete the interview testing in MATLAB or C or Java. It was reminiscent of standardized testing in some ways. As an alternative to the standardized test format there was a HackerRank coding option as well.
You will have to complete a hirevue and then a hacker rank assessment with a few coding questions and matlab multiple choice questions. You get plenty of time to complete the hacker rank assessment.
