Interviews measure interviews
Think about the last great hire you made for a talking role, and the last one that did not work out. There is a good chance both of them interviewed well. That is the hard part. An interview mostly measures how someone handles an interview, and the job is a different conversation entirely: a real customer, a real objection, a real moment where the deal can quietly slip away.
A CV tells you where someone has been. References tell you where they worked. Neither really tells you how they sound when a prospect pushes back on price, a frustrated customer needs calming, or a supplier digs in. So hiring for these roles usually leans on proxies — the polished CV, the confident interview, the strong reference — and trusts that they will carry over once the person is on a live call.
Why a live role-play does not fix it
You could test the conversation directly, but a role-play inside an interview is hard to run well. Not every interviewer can play a convincing counterpart, it takes time you rarely have, and no two candidates get quite the same conversation, so the results are difficult to compare fairly.
The comparison is the part that quietly breaks. Two candidates who faced different objections, from different interviewers, on different days have not taken the same test — and once that is true, the scores that come out of it cannot be ranked against each other, however carefully each one was given.
When the work is a conversation, watch the work
The encouraging part is that the conversation is exactly the thing you can now let candidates show you, before anyone commits.
An airline would never hire a pilot without a simulator check. When the work is a conversation, you can watch the work itself.
Every candidate handles the same realistic scenario, set in the context of your company, and is scored against the same Standard of Excellence your own team is measured on — with the evidence cited from what they actually said. Hiring then rests on demonstrated skill rather than on interview polish, and a capable person who does not interview smoothly gets a fairer shot at the role.
