The interview process at Amazon typically follows a structured framework centered around their Leadership Principles. It begins with an initial phone screen with a recruiter, followed by one or more technical phone interviews. Successful candidates are then invited to an onsite loop (now often virtual) consisting of 4-6 interviews with various team members and stakeholders. Each interview typically includes behavioral questions using the STAR method, technical assessments relevant to the role, and problem-solving scenarios. For technical positions, candidates may face coding challenges, system design questions, or case studies. The process emphasizes cultural fit and leadership potential alongside technical skills. Amazon's "Bar Raiser" program ensures hiring standards remain high, with designated interviewers specifically evaluating whether candidates raise the overall talent bar. The entire process typically spans 3-6 weeks from application to offer.
The interview process for the Software Development Engineer (SDE) role was structured and focused on assessing both technical and behavioral competencies. It began with an online assessment, which included data structures and algorithms questions. After clearing that round, I was invited to a series of technical interviews, where I solved coding problems in real-time using Python. The questions involved problem-solving, edge case handling, and time/space complexity analysis.
Additionally, I was evaluated on my understanding of core computer science concepts, such as object-oriented programming, system design basics, and debugging. The final stage involved behavioral interviews based on the company’s leadership principles and past experiences—covering scenarios like working in a team, handling failure, and ownership.

Question 1
Can you write a function to find the first non-repeating character in a string?"
This question tested my knowledge of data structures, particularly hash maps (dictionaries in Python), as well as my ability to optimize for time and space complexity. I walked through a brute-force solution first, then discussed an optimal approach using a two-pass algorithm with a dictionary.
I applied online. The process took 3 months. I interviewed at Amazon in Mar 2025
