I applied through a recruiter. I interviewed at Amazon (Portland, OR) in Dec 2016
Interview
It's Online Assessment, including 75 min for coding and 15 min for culture survey.
75 min coding: The time is limited and showed on screen, totally two algorithm questions, the library should import by yourself when coding.
15 min survey actually is not time limited.
Interview questions [1]
Question 1
1. find-all-anagrams-in-a-string
2. find common ancestor for a n-ary tree
These two questions have to use JAVA to solve.
