How interviewers test Docker
Real questions from Skilture's interview banks, with what the interviewer is listening for.
DevOps Engineer · basic
Explain the difference between a Docker image and a container, and how layers affect image size.
Listen for: Look for image as an immutable template and container as a running instance, plus using multi-stage builds and layer caching to keep images small. Confusing the two or bloated images with no cleanup are red flags.
Backend Developer · basic
Explain the concept of containerization using Docker. What problem does it solve for developers?
Listen for: A strong answer will describe containers as lightweight, portable, self-sufficient units, solving the 'it works on my machine' problem by packaging application and dependencies. Key benefits like consistency and isolation should be mentioned. A red flag is confusing containers with virtual machines.
Cloud Engineer · basic
Explain the concept of a Docker image and a Docker container. How do they relate?
Listen for: A good answer defines an image as a read-only template and a container as a runnable instance of an image, highlighting the immutability of images. A red flag is confusing the two or not understanding their relationship.
