Amazon Software Engineer(Internship) interview questions

Did some hacker rank type test as a pre-assignment. I forget which platform it was. The interview itself had 1 LeetCode easy and then Amazon leadership principles questions. The coding question was finding a number that appears only once from an array of numbers where all other number appear twice. Pretty easy but to answer the follow up of doing it is not obvious if you don't have a lot of practice with bitwise operation problems. I did well on the coding part but fumbled the leadership questions. I recommend focusing on those as the coding puzzle was a simple one.
