Can we set a standard expiration of a requisition?

Hi, we are trying to understand these questions.

• Can we set a standard expiration of a req vs. just leaving it ongoing? Such as 21 days? This is different than just setting the end date for when the req is to be unposted. We want to req to be closed after a certain number of days automatically.
  • Can it be different by template (University Recruitment, pipeline, hourly/professional)?
• Is it possible to create a notification to the recruiter when a req posting expires?
  • Assuming we can pull in the expiration date – have you seen any reports for this? Is there a field to pull in that expiration date?
