PwC Senior Devops Engineer Interview Questions, Process, and Tips

The cycle of DevOps involves continuous integration, continuous delivery, and continuous deployment to streamline software development and deployment processes.

• Continuous integration: Developers regularly merge their code changes into a central repository, where automated tests are run to detect integration issues.

• Continuous delivery: Code changes are automatically built, tested, and prepared for release to production,...read more

Branches of deployment refer to different environments where code changes are deployed for testing and production.

• Development branch - where developers work on new features and bug fixes

• Testing branch - where code changes are tested before being merged into production

• Staging branch - a replica of the production environment used for final testing before deployment

• Production branch - where the final code changes are depl...read more

Azure DevOps is a cloud-based platform for managing the entire DevOps lifecycle.

• Azure DevOps provides tools for project management, version control, continuous integration and delivery, testing, and deployment.

• I have worked on projects that involved setting up CI/CD pipelines using Azure DevOps, managing releases, and automating testing.

• For branching strategies, I have used GitFlow and Trunk-based development depending

I have worked on various projects involving infrastructure automation, CI/CD pipelines, and cloud migration.

• Implemented infrastructure as code using tools like Terraform and Ansible

• Designed and built CI/CD pipelines using Jenkins and GitLab CI/CD

• Migrated on-premises applications to the cloud (AWS, Azure)

• Implemented monitoring and alerting solutions using tools like Prometheus and Grafana

• Worked on containerization using

CI/CD pipelines are automated processes that build, test, and deploy code changes to production.

• CI/CD stands for Continuous Integration/Continuous Deployment

• CI involves automatically building and testing code changes as they are made

• CD involves automatically deploying code changes to production

• Pipelines are made up of stages, such as build, test, and deploy

• Tools like Jenkins, Travis CI, and CircleCI are commonly used f

The branching strategies commonly followed in projects are feature branching, release branching, and trunk-based development.

• Feature branching involves creating a separate branch for each new feature or task.

• Release branching is used to create a stable branch for preparing and releasing a new version of the software.

• Trunk-based development promotes continuous integration by committing directly to the main branch.

• Other ...read more
