Amazon Intern interview questions

I applied online and within a week I received an e-mail asking for suitable time for 2 phone interviews. I had two back-to-back 1-1.5 hrs interviews. The first interviewer was very rude, he called me 15 mins late and didn't even introduce himself properly before blaming me for the delay. The second interviewer was very friendly though. Both the interviewers asked me to write code on a paper and read it out.

It was a phone interview. Two interview meeting were scheduled with 15 min of time interval between them. each interview was for an hour. 1st interview was Basic data Structure questions and coding. The second one was also basic Data structure questions followed by a coding question. After interview process is over, you are free to quesiton them about the company and general doubts and after a week I got a confirmation call to join them.
