Amazon SDE intern interview questions

there was only one round in which the interviewer asked 2 questions based on data structures and algorithms. The questions were in range easy-medium. The total time took for the interview was 1 hour. The interviewer was friendly and made interview very smooth for me.

The interview has 1 round of 1 hr and asked me about my resume for 20-30 min and 1 coding question on binary. tree (medium level) and asked its approach.
