Amazon AS Intern interview questions

2 sets of 45minutes phone interview with 15 minutes break in the middle. The first round is a general data structure question. It is not that hard but you need to be familiar with frequently used data structure like arraylist, linkedlist, stack, queue, hashtable and so on to solve the problem. the second round is a harder algorithm problem.

Telephonic Interview. Had it in 2- steps of 45 minutes each with a 15 minutes break in between.
