Amazon Software Development Engineer interview questions

I applied to be an SDE Intern back in November 2018 and received a response in December for the first online assessment. I wasn't in any rush and submitted it after a week and received the second OA a few days (5) later. I submitted the second OA and 10 days later, I received an invitation to a virtual final interview. I received the email on a Monday and the first available interview was the following Monday. I had deadlines from other offers, so I sent an email to HR and fortunately, they provided me with a time for Wednesday (2 days after receiving the email). Therefore, I only had a total of 2 days to preview for the interview. Interview went smoothly and the interviewer was very nice. It was a quick brief introduction and then right into the interview (won't disclose what went on). Interview lasted an hour. I received an offer 2 days later (because I notified HR that I had a pending offer). All in all, my experience was fantastic. The HR was very responsive and I have no complaints. Excited to be interning there this summer!
