Amazon Software Engineer Internship interview questions

It felt a bit random, Selection from applicant pool to 1st round of interviews took 4 months. They are only interested in computer science related experiences, no other leadership or teamwork counts.

Got an email containing an invitation to an online assesment and another link to schedule a short online call with the recluiter in case I had any questions, I had 15 days to complete the assesment and shortly after doing so I recieved a response, where they evaluate your performance in the online assesment and decide to move forward or not depending on the result.
