GitHub Actions
GitHub Actions is a tool that helps automate repetitive tasks in software development. Think of it as a digital assistant that automatically checks code quality, runs tests, and helps publish software updates. When developers submit their work to GitHub (a popular platform where code is stored), GitHub Actions can automatically start a series of pre-defined tasks, like making sure the code works properly and getting it ready for release. This saves time and reduces human error. It's similar to other tools like Jenkins or CircleCI, but it's built directly into GitHub, which many companies already use.

Example Interview Questions
Senior Level Questions
Q: How would you design a complete deployment strategy using GitHub Actions?
Expected Answer: A senior should explain how they would plan the entire process from code check-in to production deployment, including security checks, testing stages, and approval processes. They should mention managing secrets, handling different environments, and ensuring reliable deployments.
Q: How would you optimize GitHub Actions workflows for large projects?
Expected Answer: They should discuss strategies like caching, parallel job execution, minimizing build times, and managing workflow triggers efficiently. They should also mention cost optimization and resource management.
Mid Level Questions
Q: What are GitHub Actions workflows and how do you create them?
Expected Answer: Should be able to explain that workflows are automated processes defined in special files, how to set up basic automations, and how to trigger them based on different events like code updates or time schedules.
Q: How do you handle secrets and sensitive information in GitHub Actions?
Expected Answer: Should explain using GitHub's secrets management, how to safely store and use sensitive information like passwords and access keys in workflows.
Junior Level Questions
Q: What is the basic structure of a GitHub Actions workflow file?
Expected Answer: Should be able to explain the basic parts of a workflow file: when it runs, what it does, and the basic steps involved.
Q: How do you trigger a GitHub Actions workflow manually?
Expected Answer: Should know how to run workflows on-demand using the GitHub interface and understand basic trigger events like push and pull requests.
