Have you ever met a candidate who seemed perfect but for a different position? Have you ever interviewed a newbie with great potential when you looked for experienced person? Have you ever talk with person who could work only part-time while you needed a full-timer?
You probably have.
And what was your decision?
You could follow the schema, rejecting the candidate as it wasn’t the choice you aimed for. Or better, you could break the schema and try to find the place for a talent. You could look for another team when he could suit. You could dedicate more effort to learn her basics before throwing her into deep water. You could adjust requirements a bit to include part-timers. Or maybe, just maybe, you already had way too much talent in your team.
