AI / Dependabot Interview questions
What is the difference between a Dependabot alert and a Dependabot pull request?
An alert is a notification identifying a problem (a known vulnerability affecting a dependency currently in use); a pull request is the proposed solution (a code change bumping that dependency to a fixed version). One alert can lead to a pull request, but they're distinct objects with separate lifecycles.
| Alert | Pull Request |
| Identifies a vulnerability affecting a used dependency. | Proposes an actual code change fixing it. |
| Purely informational; doesn't modify code. | Requires review/merge to actually apply the fix. |
| Persists until the vulnerability is resolved or dismissed. | Can be closed independently without resolving the underlying alert. |
This distinction matters practically: closing or ignoring a Dependabot pull request doesn't make the underlying alert go away — the vulnerability is still present until the dependency is actually updated, whether via that PR, a manually authored fix, or an alternative remediation like removing the dependency entirely.
