As an old tech giant, theAmazon The SDE OA has always been the level with the highest percentage of brushes. Not only does it test algorithms, but it also tests communication logic and scenario adaptation, and many students have fallen into the "underestimation of difficulty". Our Programhelp team has coached more than 100 students to successfully pass Amazon OA in the past few years, and today we will take you to read and understand in one article: What does Amazon SDE OA test? What do the high-frequency questions look like? How to prepare for the exam? How to prepare for the exam?
Amazon SDE OA Process Overview
| point | Description of content |
|---|---|
| OA1 | Two Algorithmic Programming Questions (LeetCode Style) |
| OA2 (partial post) | Work Simulation + LP Judgment Questions |
| Form of submission | Online system completion, 90 to 120 minutes, automatic scoring |
| Availability of retests | Basically, no, the first submission determines whether you make it to the next round or not. |
Difficulty is actually still a bit variable, normally 1 Mid + 1 Hard, but occasionally there will be two Hard, so it's a bit of a matter of luck. So it is not recommended to "brush the medium questions and then go on", it is more prudent to have some Hard questions in reserve.
Amazon SDE OA Exclusive question sharing
For Amazon SDE in North America, the OA questions used to be 2 hours, but the latest OA received this month has been extended to 3.5-4 hours!
The main types of questions are: Coding Questions, Work Simulation and Leadership Questions.
In general, the difficulty is between Easy-Medium, the questions are quite long, pay attention to the reading time High-frequency questions have changed, to collect and organize the new questions in recent months can be combined with the brush, to master the basic logic!
How to prepare for Work Simulation + LP Judgment Questions?
For SDE New Grad, many positions will also add a Work Simulation + Leadership Principles multiple choice judgment test.
Core Examination Points::
Can you show "Customer Obsession"?
There is no "Ownership" instead of dumping/relying on superiors.
There's no "Bias for Action" when it comes to problems.
