Amazon Software Developer Engineer (Internship) interview questions

The interview took place on Amazon Chime (it's an app amazon made for interviews). Interviewer asked me to give him a brief introduction about myself (took about 45 seconds). Then he asked me 3 behavioral questions. Make sure to mention Amazon's leadership principles in your answer. Note: each question had 2 - 3 parts. Then we moved on to a coding question. It was fairly easy. The problem essentially asked to create a frequency map to find the most frequent element in a list. Whole interview lasted about 45 minutes to an hour.
