Amazon Online Assessment Questions

The first step to getting a job at Amazom is to pass the online assessment, commonly referred as "OA". Candidates are sent a test with 1-2 questions to complete them within 1.5 hours. The assessment result will be used to decide if the candidate can move on to the on-site interviews.

Here we have compiled a list of all online assessment questions for you to practice so you'll be more than ready when you get the real OA.
