Amazon S3
Amazon's object storage service, the standard place cloud applications keep files. Its storage units are called buckets.
What it tells you about a developer
S3 experience mostly confirms general AWS fluency, since nearly every AWS-based product touches it. The deeper signal sits in the surrounding decisions: access permissions, storage classes and cost, and event triggers that run code when a file lands. A developer who talks about those has done real cloud infrastructure work.

S3, short for Simple Storage Service, was one of the first AWS products and remains the default home for files in the cloud. Applications store images, backups, logs, and datasets in named buckets. Its interface became an industry standard: many other vendors advertise their storage as S3-compatible.
