- Update a job
- Delete a job
And also
- Search for jobs using full-text search
- Update will trigger a background action to update external system with eventual consistency

Shortlist Candidates workflow
<img width="709" alt="Candidate Shortlisting Use Case" src="src/main/java/io/iworkflow/workflow/shortlistcandidates/use_case.png">See ShortlistCandidates for how to build a workflow to automatically establish connections with shortlisted candidates on behalf of an employer.
- Design a workflow as long-term storage: leveraging the attributes of iWF to retain the employer opt-in information in EmployerOptInWorkflow.
- Retrieve the attributes of another workflow from within a different workflow: checking the employer's opt-in status stored in the EmployerOptInWorkflow when making a decision on whether to automatically contact shortlisted candidates for that employer in the ShortlistWorkflow.
