Summary
Who is a short, methodical book about hiring — specifically about why most companies make the same predictable mistakes when choosing people, and how a structured process called the A Method can fix them. Smart and Street, both management consultants, argue that the single biggest lever leaders have is picking the right people. Most organizational dysfunction traces back to hiring errors, and most hiring errors are avoidable.
The core of the book is a four-step process. The first step is the Scorecard: before you talk to anyone, define the outcomes the role must achieve and the competencies required to achieve them. The second is Sourcing: treat talent-finding as a continuous activity, not a crisis mode you enter when someone quits. The third is Selection, which involves four types of structured interviews — the screening interview, the Who interview (a chronological career walkthrough), the focused interview, and the reference interview. The fourth is Selling: once you've found the right person, close them by addressing the five things most candidates care about.
The Who interview is the book's most distinctive contribution. Rather than asking hypothetical questions ("what would you do if..."), interviewers walk candidates through their entire work history year by year, asking the same five questions about each role: what were you hired to do, what accomplishments are you proud of, what were the low points, who did you work for and how would they rate you, and why did you leave. This structured walk reveals patterns that hypothetical questions miss.
Smart and Street make a credible case that most interviewers are winging it — running on gut instinct and hoping for the best — and that this produces mediocre results at predictable rates. The book is prescriptive almost to a fault: it tells you exactly what to ask, in what order, and how to interpret answers. That's a feature for practitioners who want a repeatable system, and a limitation for readers hoping for deeper psychological insight into why people succeed or fail in roles.

Key takeaways
- 1.
The most expensive mistake in business is a bad hire. Smart and Street estimate that a mis-hire costs up to 15 times the person's annual salary when you include lost productivity, morale damage, and rehiring costs.
- 2.
Start with a Scorecard, not a job description. Define the three to eight outcomes the role must achieve in the first year, then list the competencies required to deliver them.
- 3.
The Who interview is a structured walkthrough of a candidate's entire career. Five questions per role, asked chronologically, reveal behavioral patterns that situational questions hide.
- 4.
Always ask 'what would your former boss say were your biggest strengths and weaknesses?' Candidates answer this more honestly than direct questions because they're imagining a reference check.
- 5.
Reference calls are underused and often mishandled. Call the references you find yourself — not just the ones the candidate provides — and use the same structured questions.
- 6.
Sourcing should be continuous, not reactive. Great companies maintain a warm pipeline of A-players rather than scrambling to fill roles after someone leaves.
- 7.
When selling a finalist candidate, address the five things they care about: fit with the mission, role clarity, development opportunity, team quality, and compensation.
- 8.
Vague interviews produce vague data. Every structural feature of the A Method — fixed questions, chronological order, numerical ratings — exists to reduce noise and surface signal.
Discussion questions
Use these on your own, with a book club, or as chat starters in Superbook.
- 1.
Smart and Street claim the biggest mistake leaders make is a bad hire. Does that match what you've seen in your own organization or career?
- 2.
Have you ever sat through a job interview — as interviewer or candidate — that felt obviously poorly designed? What made it ineffective?
- 3.
The Who interview requires walking through every job in a career. What would that reveal about your own career that a typical interview would miss?
- 4.
The book argues that most interviewers rely on gut feel, and that gut feel is largely unreliable. How much do you trust your own instincts when evaluating people?
- 5.
A Scorecard defines outcomes, not just activities. Take a role you know well — what three outcomes would define success in the first year, and how would you measure them?
- 6.
The authors recommend asking candidates what their former bosses would say about them. Does this question make you more or less likely to get an honest answer, and why?
- 7.
What's your organization's actual sourcing process? Is it reactive or proactive, and what would it take to shift toward continuous pipeline building?
- 8.
Smart and Street say A-players want to work with other A-players. Have you experienced that pull — or its opposite, a culture that repels high performers?
- 9.
The book is very prescriptive about interview structure. When, if ever, is improvising in an interview better than following a script?
- 10.
Reference calls are described as gold but typically treated as a formality. What would you need to change about how your team does reference checks?
- 11.
The book focuses almost entirely on selection, not retention. What does it leave out about keeping A-players once you've hired them?
- 12.
If your team ran the full A Method for every open role, what's the biggest organizational obstacle you'd face?
Themes
Frequently asked questions
-
Is Who worth reading for managers?
Yes, particularly for anyone who hires regularly and has made a bad hire they're still paying for. The book is prescriptive and short. If you want a structured process you can implement immediately, it delivers one. If you want a deeper theoretical treatment of talent assessment, pair it with Work Rules or First, Break All the Rules.
-
How long does it take to read Who?
Around three to four hours. The book is under 200 pages and the prose is direct. Most readers can finish it in a weekend and leave with a clear action plan.
-
What is the A Method for hiring?
A four-step process: Scorecard (define the role's required outcomes and competencies), Sourcing (build a continuous pipeline), Selection (four structured interviews including the career-history Who interview), and Selling (close the right candidate by addressing what they care about).
-
Who should read this book?
Founders, managers, HR professionals, and anyone who has made a hiring mistake they could trace back to a weak selection process. It's also useful reading for job candidates who want to understand how rigorous interviewers think.
-
What's the most actionable idea in Who?
The Who interview: walk candidates through their entire career chronologically, asking the same five questions about each role. It takes longer than a typical interview but produces far richer signal about patterns of behavior than any hypothetical question can.
