Amazon Non Software Development Engineer interview questions

I got a call from HR, we discussed my previous work experience and scheduled an online assessment. I had to ask for more time to complete the OA because of my exams and feeling sick with covid. I did the OA, aced the two coding questions (one LC easy and one LC medium). But I got a rejection email saying I was not selected without any detailed feedback. It can be that I took more time to complete OA or I did bad on behavioural questions in the OA.
