How to Run an Executive Reference Check
Run executive reference checks as a structured conversation — not a box-ticking exercise. Call at least three references: one who has managed the candidate, one who has been managed by them, and one peer. Ask open-ended questions that invite specific stories, not yes/no assessments. The CEO should conduct at least one reference check personally — it signals the importance of the hire and often yields the most candid information.
Reference checks are the most underutilised assessment tool in executive hiring. They are treated as a formality — a series of polite calls that confirm what was already decided. Done properly, they are the highest-signal data point in the process, often revealing patterns that four rounds of interviews obscured.
Reference Check Process
| Step | Action |
|---|---|
| 1. Who to call | Former manager, former direct report, former peer — in that order of priority |
| 2. How many | Minimum 3, ideally 5 for C-suite roles |
| 3. Who conducts | CEO conducts at least 1; search firm handles others with structured guide |
| 4. Duration | 20–30 minutes per reference; do not rush |
| 5. Timing | After final interview but before offer; never as a formality after offer is verbal |
The Best Reference Check Questions
| Question | What You Are Learning |
|---|---|
| In what context did you work with [candidate]? | Validates claimed relationship and tenure |
| What were their greatest strengths in that role? | Confirms what interviews suggested |
| Where did they struggle most? | Often reveals the critical pattern interviews hide |
| How did they handle a significant failure or setback? | Tests resilience and accountability |
| What would they need to change to be excellent in a VP-level role? | Most revealing question — forces specific insight |
| Would you hire them again? For what role specifically? | The 'for what role specifically' often reveals stage-fit concerns |
Backchannel References
Beyond provided references, conduct 1–2 backchannel references — people in your network who have worked with the candidate but are not on their reference list. LinkedIn and investor networks are the fastest path. Backchannel references are more candid because the candidate has not primed them. For senior roles, backchannel references are essential, not optional.Red Flags in Reference Responses
Pause immediately if: (1) the referee cannot give a specific example for any strength or development area, (2) the referee seems uncomfortable describing the candidate's management style, (3) they hedge on whether they would hire again, or (4) the role they describe the candidate as suited for is consistently more junior than the role you are hiring.Frequently Asked Questions
Should the candidate choose their own references?
Yes — but ask for more names than you will call, and select which ones you contact. Also conduct at least one backchannel reference that the candidate has not provided.
What if a reference will only confirm dates of employment?
This itself is a signal — it often indicates a legal policy at the employer. Ask if there is anything they are able to share informally. If they decline entirely, ask the candidate to provide an alternative reference from that period.
Can you call references before a verbal offer?
Yes, and this is the recommended approach. Calling references after the verbal offer is a formality; calling before gives you real leverage — if a red flag emerges, you have not already committed.
