I applied online. The process took 4 weeks. I interviewed at Amazon in Dec 2018
Interview
Online Debugging/Logic Challenge -> Coding Challenge -> Video Technical Interview with SDE.
I also applied in August and they didn't get back to me in December, their HR is pretty bad in my opinion.
Debugging and logic was pretty easy, just understand logic and be able to trace code to see what's wrong. Coding challenge was alright, one was to reverse a linked list and the other was to make an MST. Video one was tough (for me), but I've had friends who got easy stuff like Two Sum, buy and sell a stock once, largest/smallest k numbers in an input stream, etc.
Just do leetcode and you're chillin.
Interview questions [1]
Question 1
Q: You are given an R*C matrix with distinct integers [1,..,R*C]. You start at the top left corner and want to get to the bottom right. You can only move down or to the right, return the smallest lexicographical path.
