I interviewed at Amazon Web Services (Dublin, Dublin)
Interview
The process started with an online assessment (OA) consisting of coding questions and a work simulation style section. The coding questions focused on data structures and problem solving.
After passing the OA, I had a final round interview which was technical and behavioural. The technical portion involved writing code live and explaining my approach clearly. There were also questions around system design fundamentals and troubleshooting scenarios relevant to infrastructure.
The behavioural questions were based heavily on Amazon’s Leadership Principles, so I would strongly recommend preparing specific examples using the STAR method.

I applied online. I interviewed at Amazon Web Services (Seattle, WA) in Nov 2025
Interview
Relatively simple interview process. Received OA a few weeks after applying. 3 easy questions for OA. Received interview invite a week after passing OA. Interview was 1 easy coding problem that you were given 30 minutes to solve. Finished early so they just ask me some general operating system questions. Rest of the time was spent with questions with leadership principles in mind.
