DevOps / GitLab CI Basics Interview Questions

What is the 'timeout' keyword in GitLab CI and what are the defaults?

The timeout keyword sets the maximum duration a job is allowed to run before GitLab forcefully stops it. Timeouts prevent hanging jobs from blocking runners and consuming resources indefinitely.

# Job-level timeout
long-running-test:
  script:
    - run-full-integration-tests.sh
  timeout: 2 hours             # stop after 2 hours

build-job:
  script:
    - make build
  timeout: 30 minutes          # stop after 30 minutes

# Timeout format examples:
# timeout: 3600         (seconds)
# timeout: 60 minutes
# timeout: 2 hours
# timeout: 1h 30m
# timeout: 1 day

# Default timeout hierarchy:
# 1. Job-level timeout (if set)
# 2. Project-level timeout (Settings > CI/CD > General pipelines)
# 3. Runner timeout (set when runner is registered)
# The smallest of project timeout and runner timeout applies,
# then job-level timeout can only be lower than that

Timeout hierarchy
LevelWhere setDefault
Jobtimeout: keyword in jobNo default (uses project or runner)
ProjectSettings > CI/CD > General pipelines60 minutes
RunnerRegistered runner configNo limit (unlimited)

Key rule: a job timeout cannot exceed the project-level timeout or the runner's maximum timeout. If you set a job timeout longer than the project timeout, the project timeout wins.

What is the default project-level job timeout in GitLab CI?
If a job sets timeout: 2 hours but the project-level timeout is 60 minutes, how long does the job run?
