Just Received Amazon OA Request — Tips for SDE II L5 Applicants in Canada

As a software engineering candidate, receiving an Online Assessment (OA) request from Amazon can be both exciting and nerve-wracking, especially for a Level 5 (SDE II) position. If you’re relatively new to LeetCode but have a good grasp of Data Structures and Algorithms (DSA), you’re already on the right track. In this post, I’ll share insights and tips to help you prepare effectively over the next week.

Understanding Amazon’s Online Assessment

Amazon’s OAs are known for their rigorous testing of algorithmic skills and problem-solving abilities. Unlike many other companies, Amazon’s assessments often focus on a combination of coding problems and behavioral questions that reflect their Leadership Principles. Thus, it’s essential to not only brush up on algorithms but also to understand Amazon’s culture and values.

Preparation Strategy

1. Focus on Patterns and Depth:

   • You mentioned prioritizing depth and pattern recognition over volume, which is a smart approach. Understanding common patterns in problem-solving (like sliding window, two-pointer technique, and dynamic programming) can significantly improve your efficiency during the assessment.
   • Consider solving problems from the Neetcode 150 list. This curated selection helps you focus on key problems that are frequently seen in interviews.

2. Leverage LeetCode Premium:

   • Investing in LeetCode Premium will give you access to tagged problems that are specifically relevant to Amazon. This focused practice can help you familiarize yourself with the types of questions you might encounter.
   • Make sure to utilize the discussion forums on LeetCode to understand different approaches to the same problem, which can provide you with varied perspectives and solutions.

3. Mock Interviews:

   • If you’ve had positive results in Live OA sessions with other companies, consider conducting mock interviews with peers or using platforms like Pramp or Interviewing.io. This can help simulate the pressure of the actual assessment and improve your time management skills.

4. Behavioral Questions:

   • Don’t neglect the behavioral component of the OA. Prepare for questions based on Amazon’s Leadership Principles. Use the STAR (Situation, Task, Action, Result) method to structure your responses effectively.

Time Management

Regarding your concern about asking for more time, it’s generally advisable to gauge your comfort level first. If, by the end of the first week, you feel significantly unprepared, reaching out to request an extension can be beneficial. Just ensure that your request is polite and emphasizes your desire to deliver your best work.

Additional Resources

• YouTube Channels: Channels like “TechLead” or “Clément Mihailescu” offer insights into coding interviews and can provide you with useful tips and tricks.
• Books: If you have time, consider reading “Cracking the Coding Interview” by Gayle Laakmann McDowell, which covers a wide array of topics and provides valuable problem-solving strategies.

Conclusion

Preparing for an Amazon OA can seem daunting, but with focused practice and a strategic approach, you can enhance your chances of success. Remember that every candidate’s journey is unique, so find what works best for you and stick to it. Best of luck with your assessment! You’ve got this!
