Hoffman says he would choose references over interviews because candidates can rehearse interviews while some excellent performers do not sell themselves well. The strongest process uses off-balance references: people found through the network rather than only the list a candidate supplies. In each call, establish that everyone has both strengths and weaknesses, then explain that a refusal to name any weakness will itself be interpreted negatively. Probe polite labels until they describe observable work behavior. Carry a theme from one call into the next to gain context and corroboration. The final decision asks whether the candidate's particular trade-offs fit the role, not whether the person is flawless.

How to run it
- 1
Build an independent list
Use trusted network paths to identify people who directly observed the candidate's work, including references the candidate did not supply.
Pro tip LinkedIn can help reveal shared professional ties.
Watch out Respect confidentiality and applicable hiring rules.
- 2
Establish the premise
Tell the reference that every person has strengths and weaknesses and that you need both to assess fit.
- 3
Force specificity
Ask for a real weakness and explain that claiming none exists will make you infer that the hidden issue is serious.
Pro tip Ask for an example of when the behavior affected work.
Watch out Do not treat a single uncorroborated opinion as fact.
- 4
Decode euphemisms
Translate labels such as perfectionist into concrete effects on speed, organization, judgment, or collaboration.
Pro tip Ask what the manager had to do differently because of it.
- 5
Triangulate and decide
Ask later references about the same theme, then evaluate the whole strength-and-weakness combination against the job.
Watch out Fit for one role does not establish universal ability or inability.
In the wild
A reference calls a candidate a perfectionist. Instead of accepting the compliment-like label, the checker asks whether this meant slower delivery or poor prioritization. The next reference is then asked whether they observed the same behavior and under what conditions.
→ A vague label becomes role-relevant evidence that can be corroborated.
Common mistakes
Using only supplied references
Candidate-selected references are more likely to be chosen for favorable answers and may omit important perspectives.
Searching for a flawless person
The method assumes everyone has trade-offs and evaluates whether the combination fits the role.
Is it for you?
Best for
Hiring consequential employees or executives whose past work can be independently checked.
Not ideal for
Candidates with no work history or accessible observers, where a practical work test may be more informative.
From the transcript
