What is the difference between a Docker image and a Docker container? Explain how layers work in a Docker image and how they affect build caching.

Answer:
A Docker image is a read-only template that packages your application code, runtime, libraries, and system tools into a single artifact. A Docker container is a running instance of that image — it adds a thin writable layer on top where runtime state like logs, temp files, and in-memory data live. The key difference: images are immutable and shareable, while containers are ephemeral and isolated. You can spin up hundreds of containers from the same image, and each one gets its own writable layer without affecting the base image. Regarding layers — every Dockerfile instruction (FROM, RUN, COPY, ADD) creates a new layer. These layers are

Your data is safe

Built privacy-first.

Interviews are personal, so you decide where the record of yours lives: in your LastRound AI account, or only on the computer you ran it on. Either way we never share, sell, or publish your content.

Keep it on your machine

Choose “Keep on this device only” in the desktop app and the record of your interview is written to your own computer instead of your account. We keep no copy, so there’s nothing on our side to look up later.

Yours alone

Saved to your account instead? It’s locked to you. No other user — and no one on our team — can see what you said or how you answered.

Still yours to review

On-device history opens in the desktop app, or in Chrome and Edge straight from your browser — your computer hands the files to the page, so no copy is uploaded.

Encrypted in transit

All connections use TLS 1.2+. Anything you do save is encrypted at rest via Supabase managed Postgres.

Full details in our Privacy Policy.

Ready when you are.
