Why Your Interview Panel Can't Agree on Anyone
Five interviewers, five different standards. The same candidate scores a 2 from one panelist and a 9 from another, and there's no fair way to compare.
It's one of the most common, and least discussed, failures in hiring: put the same candidate in front of five different interviewers, and you'll often get five meaningfully different opinions. Not slightly different. Sometimes a 2-out-of-10 from one panelist and a 9-out-of-10 from another, for the exact same conversation.
This isn't because one interviewer is "wrong." It's because "how would you rate that candidate" is a question with no shared reference point. One interviewer's 7 is another's 5, because they're each silently comparing the candidate to a different mental bar, their best report, their worst hire, the last three people they interviewed this week.
Why this matters more than it seems
When scores aren't comparable across interviewers, the hiring decision quietly becomes a function of who happened to interview the candidate, not how the candidate actually performed. A great candidate who draws a tough interviewer gets passed over. A mediocre one who draws a lenient interviewer sails through. Multiply that across dozens of hires a year and it's not a rounding error, it's a structural flaw in who gets hired.
What a shared rubric solves
The fix is to remove subjective scoring from the loop entirely and replace it with a rubric that's defined once, before any interviews happen, and applied identically to every candidate: the same weighted skills, the same MUST vs. NICE-to-have breakdown, the same scoring criteria per answer. When every interview, whether it's conducted by a person or an AI interviewer, is scored against the same fixed rubric, a 7 means the same thing every time.
This is also what makes candidate comparisons actually defensible. If two candidates are both scored against identical weighted criteria, you can rank them with confidence, and just as importantly, you can explain exactly why one was ranked above the other if anyone ever asks.
The takeaway
Consistent hiring isn't about finding better interviewers. It's about removing the need for every interviewer to independently invent their own definition of "good," and replacing it with one rubric that every candidate is measured against the same way.
