Amazon Internship interview questions

I applied through on campus process. I submitted my resume' , after about 3 months when I thought I failed, I received a phone call from Amazon's recruiter to schedule first round interview. The first round interview had 2 back to back 30-minutes interviews. I heard about the result few days afterward for the final round. The final round was another back-to-back 45-minutes interviews. This went well. And about 1 week later I heard about the offer

The first round there was two parts, one where you had to debug some code and one critical thinking section. The second round contained two basic coding questions and general questions about personality.
