Hi guys

Here is the summary of my amazon experience, from phone screen to offer for a position in NYC.

Phone Screen:

• Started off with behavioral questions:
  • What are you currently working on?
  • What’s the most creative thing you’ve done?
• Add new connection

Onsite (Friday):

Round 1:

• Behavioral questions:
  • Tell me about a time when you were not satisfied with status quo.
  • Tell me about a time where you had to persuade your coworkers.
• Design a chess game (design question turned into a coding question):
  • What are the classes
  • Inheritance chain
  • Write an algorithm to find all the valid moves for a rook

Round 2:

• Behavioral (lots of them):
  • Tell me about yourself
  • Behavioral questions regarding how I would persuade coworkers, how I would get things done.
• https://leetcode.com/problems/implement-strstr

Round 3:

• Behavioral questions
• You have tasks that depend on other tasks to be completed before they can complete. You are given a list of tasks and their dependencies, can they all complete? It's topological sort: https://leetcode.com/problems/course-schedule-ii

Round 4: [with 2 managers]

• These two guys were awesome and haven’t been at amazon for a long time. We chatted about Seattle, reconciliation systems. Asked me why Amazon?

• Design Question: You have a start-up that plan planted 1 million sensors across the USA. We have to know:

  • Temperatures in real time in a map
  • Historical data: low and high for the day going back to 5 years
  • Sensors send 1KB of data every 10 second.

  I came my answer based on geo hashing. They loved the answer.
