How COOs Can Build a Better Hiring System

Executive overview

The wrong hire costs one times salary to replace — but keeping the wrong person in the role costs 15 times salary in opportunity cost, mistakes, and damage. Most managers interview without any formal training, and most companies have no system for it.

The fix is a four-part foundation built before any ad is posted: a clear job description with measurable outcomes, an ideal candidate profile (behavioral traits, core values, proven skills), a scorecard to assess candidates consistently, and a job advertisement written to attract A-players and repel everyone else.

Hiring is a learnable system — and the cost of not learning it dwarfs the cost of learning it.

The four-part hiring foundation

• Start with measurable outcomes: what must this person achieve, by when?
• Define the behavioral traits and core values the candidate must already hold.
• Hire for "has done it" not "knows how to do it."
• Build a scorecard so every interviewer rates candidates against the same criteria.

Job description vs. job advertisement

• A job description states requirements; a job advertisement sells the role.
• Most postings on Indeed are boring descriptions — they attract boring candidates.
• Have a copywriter rewrite your job posting; HR staff rarely have copywriting training.
• Make the posting polarising: the right person should feel it was written for them; the wrong person should self-select out.

Building interviewing skill

• Interviewers need at minimum 20–30 hours of training to become competent.
• Core techniques: open and closed questions, pregnant pauses, the reverse sell, probing follow-ups.
• Record interviews and review them; debrief on every mis-hire by going back to the original notes.
• The learning cycle: read or watch (abstract conceptualization) → practice with role-plays (active experimentation) → do real interviews (concrete experience) → review recordings (reflective observation) → repeat.

Practical starting points for entrepreneurs

• Identify who in your team already has aptitude for hiring — don't rely on the blind leading the blind.
• Have managers read chapter two of Double Double for the foundational interview process.
• Find two or three free YouTube videos on interviewing technique and assign them to your team.
• Re-read the material quarterly; mastery requires repeated cycles, not a single pass.
• The time spent hiring well is always less than the time spent managing a bad hire.
