I received an Online Assessment (OA) invitation from Amazon. The assessment consisted of two coding questions of medium to hard difficulty, focusing on data structures, algorithms, and problem-solving skills. The questions required efficient solutions with optimized time and space complexity. After the OA, shortlisted candidates typically proceed to one or more technical interview rounds covering coding, system design, and behavioral questions based on Amazon's Leadership Principles.
Applied online via career site, received OA link within 2 days and cleared it, Round 1- DSA, Round-2 DSA, Round 3- System Design, Round 4- Mixed Technical Discussion and Behavioral.
