Amazon SDE Intern interview questions

Fall internship offer. 2 technical rounds ( Both were leetcode questions, medium) and 1 behavioral on amazon principles( Prep materials shared by the recruiter). I got the offer after 2 weeks.

The process was quite simple. 1) They started with a quick introduction of themselves followed by my introduction. 2) Then they opened online editor and gave me 2 questions. One of them was based on trees and the other one was on 2d arrays. 3) A strange thing was that they only asked 2 coding questions nothing else no oops, os , dbms ,projects ,system design etc
