Amazon Web Services Front End Developer interview questions

There were three rounds of interviews in total. The first round was tech (leetcode) + behavioral questions (BQ). The second round was purely technical, where I got a LeetCode-style island problem. The third round was purely behavioral, covering some standard questions.

I recently went through the AWS Front-End interview process and documented my experience in two parts. The process started with an online application, followed by a technical phone screen that focused on data structures, DOM manipulation, and leadership principles—lasting around 45 minutes. After clearing that, I was invited to a virtual onsite loop consisting of three back-to-back interviews over two days, covering front-end coding, system design, and behavioral questions. Overall, the difficulty level was high, especially because none of the code was executed—so clear logic and structured thinking mattered most. It was intense but rewarding, and I shared everything I learned to help others prepare.
