Amazon Online Assessment Questions 2021 Preparation

The first step to getting a job at Amazon is to pass the online assessment on platforms such as Hackerrank or Codility, 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.

Note that these are prep questions. We do not know what the actual questions are but these questions are a great practice.
