Amazon’s online assessment, often called the OA, plays a major role in the hiring process—especially for international students hoping to land a tech job and stay in North America. If you're aiming for a software engineering or technical position, clearing this assessment is the gateway to getting an interview. So, preparing in the right way really matters.
The OA usually includes two coding questions and several multiple-choice ones. The coding part checks how well you understand algorithms, how you write code, and how efficient your solutions are. Difficulty can vary from medium to a bit tricky, and the most common topics involve arrays, strings, hash tables, and sometimes tree-based questions. To get comfortable with these problems, it’s a good idea to regularly practice on sites like LeetCode. It also helps a lot to stick with one main language—like Python or Java—so you can code quickly and clearly during the test.

The multiple-choice section usually focuses on computer science basics. You might be asked about data structures, time complexity, or memory management. Even though this part is often less stressful than the coding tasks, it still requires a strong foundation. Reviewing key CS concepts from your coursework before the OA can help prevent surprises.
Strategy is another part you shouldn’t ignore. Since the test is timed, it’s important not to spend too long on any single question. Time management makes a big difference—make sure you leave enough time to finish everything. Also, check your internet connection and testing environment before the assessment starts. Technical glitches can throw you off, and it’s best to handle those before they become a problem.
Once you pass the OA, you’ll likely be invited to the next rounds, like technical interviews or team matching. Amazon puts a lot of value on how people think and solve problems, so even if your background isn’t perfect, doing well on the OA can still move you forward.
Overall, the OA might just be the first step, but it’s a big one. For international students who want to build a future in North America’s tech world, it’s a chance to prove they’re ready. If you stay calm and prepare well, it can set the tone for the rest of the process.
