MathWorks Software Engineer: EDG Team interview questions

Got an hacker rank assessment, hire vue interview after the initial application. The assessment had 5 aptitude questions, 2 coding challenges in Java. Both were hard. Was able to solve them only partially(few test cases passed). Got a reject after the assessment.

I gained contact through a job fair, after which I was emailed and received a standard HR interview and a Technical Interview. I was then brought for an on-site interview. They showed us the campus and gave us additional Technical Interviews, a Manager Interview, and another HR Interview. Interviews were all pretty standard, nothing too tricky.
