Amazon Advertising Software Engineer Interview Experience: DSA, low-level design, and leadership principles

My process had four rounds. I began with DSA, then had two low-level-design rounds. One of those LLD conversations included gen-AI best practices, which was an unexpected addition to a systems-focused design interview.

The final round was entirely about leadership principles and behavioral questions. Leadership-principles questions also appeared in the earlier technical rounds, so coding, design, and behavioral framing all connected to how I think and operate.

The overall difficulty felt average. I did not receive an offer, but I came away feeling that they were looking for consistency across those modes rather than treating behavior as an afterthought.

Location: United States. Overall feedback: positive. Offer status: no offer.
