Amazon Software Development Engineer Intern interview questions

Got an OA after passing resume screen, pretty simple (2 lc meds). After passing I was invited to interview. Interviewer didn't show up so they had to reschedule. Rescheduling took around 3 months and eventually also passed the interview however I was first put on a waitlist. About 3 weeks later I was extended an offer.

First half was behavioural then a short amount of time on DSA fundamentals and finally a leetcode problem. They also asked how I would test my solution in practice at the end.
