What it includes
A complete requisition defines the role, the salary budget, the competency profile, the real urgency, and who approves the final hire. It sounds bureaucratic, but it prevents weeks of chasing a moving target.
Why this step gets skipped
On small teams or under real urgency, it is tempting to jump straight from we need someone to posting the role. The problem shows up two weeks later, when the hiring manager rejects candidates for reasons that were never written down.
The cost of not having one
Without a clear requisition, the recruiter works against a moving target: the profile shifts depending on who you ask, and the process drags because every rejection means re-guessing.
