Amazon Software Engineer (internship) interview questions

first was OA round then in the interview round they asked just two DSA questions but they wanted to know more about approach rather then the answer. If your fundamentals on DSA are aclear and crisp you might be able to crack the job

online interview, the interviwer is not very open to talk, ignored me when I tried to share some ideas of my solution. not a very good experience because lacking of communications. the interviewer looks not very happy from the beginning of interview.
