Amazon Software Intern interview questions

The first step was online HackerRank questions (medium, hard) both of which were extremely difficult for their category. Question-wording was also unclear for both of them it took me more than 20 minutes to understand what the questions were asking.

There were two oa and one interview. The interview was about 45 mins. First 15 mins for behavior questions and 30 mins for coding. I didn't get the offer, even though I worked out the coding question.
