Describe the architecture and main stages of the automated build and deployment process used at your previous job.

The automated build and deployment process typically includes several stages:

1. Build — compiling source code, assembling binary files or artifacts. In Go, this is usually go build.

2. Testing — running unit and integration tests to verify correctness.

3. Static analysis and linting — checking code for errors and style.

4. Creating artifacts — packaging binaries, creating Docker images.

5. Deployment — automatically deploying to test or production servers.

6. Monitoring and notifications — tracking build and deployment status, notifying the team.

The architecture is usually based on CI/CD systems (Jenkins, GitLab CI, GitHub Actions), which are triggered upon push to the repository.

Example of a simple pipeline in GitLab CI for Go:

stages:
  - build
  - test
  - deploy

build-job:
  stage: build
  script:
    - go build -o myapp

test-job:
  stage: test
  script:
    - go test ./...

deploy-job:
  stage: deploy
  script:
    - ./deploy.sh
  when: manual

This process ensures reliability and repeatability of build and deployment.
