Amazon OA 讲解Online Session Review

OA

Coding and Workstyle Assessment

• Knowledge of basic programming
• Data Structures & Algorithm
• Computer Science Fundamentals
• Amazon's Leadership Principles

Simulation

• Day-in-life of a SDE
• Different Scenarios with Options to pick from

Key Take-aways

• Take on the demo and practicipate in Study Session before you jump into the OA.
• Read the description and ensure you understand what the question is asking(sample input/expect output can help you gain clarity), consider any potential edge-cases.
• Plan out of your solution before jumping into coding(Paper can work).
• Do a fast version of the code and iterate to see how you can improve on it.
• Separate the code into different methods, add comments as needed to help you understand the whole problem. Even if you finish early, try to see if you can make improvements.
• Manage your time well. There are two questions. So split the time well.

自己的错误经验

• 之前日本公司发OA的时候，没有take on the demo and practicipate in study session。当发现是新题型的时候很恐慌。
• Twitch OA 自己没有认真做，很简单的5道题 因为太简单了做的很慢。导致没有manage the time well. 最后时间不够多。
• 以上经验适合做任何OA
