The Amazon Software Development Engineer (SDE) interview process typically consists of three main stages: an Online Assessment, a Phone Screen, and the Onsite Interviews (commonly called “The Loop”). The Online Assessment includes coding challenges and behavioral evaluations based on Amazon’s Leadership Principles. If successful, candidates move on to a Phone Screen, where they solve one or two coding problems in a shared editor while explaining their thought process. The final stage, The Loop, involves four to five back-to-back interviews covering algorithms, system design (for experienced roles), and behavioral questions, including a session with a "Bar Raiser" who ensures a consistent hiring standard. Throughout the process, strong coding skills, problem-solving ability, and alignment with Amazon’s culture are critically assessed.
