Chief of Staff Interview Guide
A structured Chief of Staff interview guide covering strategic prioritisation, cross-functional execution, influencing without authority, proxy judgement and discretion — with follow-up probes and a practical scorecard.

Hiring a Chief of Staff is uniquely difficult because the role defies a simple definition. It changes with the needs of the CEO and the business. The wrong hire becomes an expensive assistant. The right one becomes the operational partner that makes the CEO and the leadership team dramatically more effective. This guide gives you a structured framework: evidence to look for, questions to ask with follow-up probes, and a practical scorecard.
These indicators are prompts for structured evaluation, not model answers. Candidates may demonstrate competence through different examples or approaches. An unfamiliar answer is not automatically a weak answer — use follow-up questions before reaching a conclusion. "Not enough evidence" is a valid scorecard outcome. The final decision remains with the human hiring team.
Who this guide is for
For CEOs and founders appointing a Chief of Staff, and for leadership teams who will work closely with the role.
Role overview
A Chief of Staff is the CEO’s strategic partner. They are responsible for translating the CEO’s priorities into action, driving cross-functional initiatives, preparing the leadership team, managing strategic projects and often acting as a proxy for the CEO in specific situations. The role is not an executive assistant — it requires strategic thinking, the ability to influence without authority, and the judgement to represent the CEO accurately. The role varies enormously by company stage and the CEO’s working style.
How the role varies
At a startup the Chief of Staff may be the CEO’s only partner across everything, from strategy to operations. At a scale-up the role often focuses on strategic initiatives and leadership-team operations. In a large organisation it may specialise in board governance, corporate development or a specific business unit. The role also varies with the CEO’s working style — some need a sounding board, others need an executor.

What the interviewer should assess
A Chief of Staff interview should test four areas: strategic thinking and prioritisation, cross-functional execution, influencing without authority, and judgement and discretion. Each matters — a brilliant project manager who cannot think strategically is as risky as a strategic thinker who cannot execute.
Role-specific competencies
Strategic thinking and prioritisation
Can they distinguish between urgent and important? Do they help the CEO focus on what matters, not just what is loud?
Cross-functional execution
Can they drive initiatives across functions they do not own? Do they hold people accountable without being their boss?
Influencing without authority
Can they get things done through persuasion, not hierarchy? Do they understand the difference between authority borrowed from the CEO and authority earned through credibility?
Judgement and discretion
Can they handle sensitive information appropriately? Do they know when to act on the CEO’s behalf and when to defer?
Communication and proxy ability
Can they represent the CEO accurately in meetings and communications? Do they understand the CEO’s thinking well enough to extend it without distorting it?
Adaptability and context-switching
Can they move from a board-level strategy discussion to a tactical operational problem without losing effectiveness? Do they thrive in ambiguity?
Recommended interview structure
A 60-minute interview is a useful starting point for this role, though the Chief of Staff is best assessed across multiple shorter sessions with different stakeholders. Consider three 30-minute conversations: one with the CEO to test working alignment, one with a leadership-team member to test cross-functional credibility, and one structured interview covering prioritisation and proxy judgement. If a single session is more practical, structure it in three parts: a brief career discussion (5 minutes), prioritisation and proxy scenarios (35 minutes), and the candidate’s questions (15 minutes). Include a scenario that tests how they handle representing the CEO in a difficult situation.
Adapt this guide to your role
This guide is a starting point. Adapt it to your context. At a startup, the Chief of Staff may be the CEO’s only partner across everything — test for breadth, adaptability and willingness to be hands-on. At a scale-up, the role often focuses on strategic initiatives and leadership-team operations — test for cross-functional execution and influencing. In an SME, the role may blur with operations or HR. In a large organisation, it may specialise in board governance, corporate development or a specific business unit — test for stakeholder management and discretion. B2B and B2C contexts create different demands on the CEO’s time and the Chief of Staff’s priorities. Regulated industries add governance and compliance dimensions to the role. A co-located leadership team needs different working patterns from a distributed or hybrid one. Above all, calibrate the questions to what the specific CEO needs from the role.
Interview questions
Ask the same core questions to every candidate for this role. Use the follow-up probes to clarify vague answers and gather more evidence before scoring.
1. The CEO has ten priorities and the capacity to focus on three. How do you help them decide which three?
What this is assessing: Prioritisation judgement. Whether they can help a leader focus. Whether they have a framework for distinguishing important from urgent.
Follow-up probes
- How do you help the CEO let go of the priorities they drop?
- What would you do if the CEO kept adding priorities back?
- How do you communicate the decision to the rest of the team?
Evidence that may indicate strength
- Evaluates each priority against the business strategy
- Considers the cost of not doing something, not just the benefit of doing it
- Looks at dependencies between priorities
- Helps the CEO see trade-offs rather than just ranking
Points that may require further probing
- Takes the CEO’s ranking without question
- Has no framework for prioritisation
- Focuses on effort rather than impact
- Does not consider what to stop doing
2. You are asked to drive an initiative across three departments whose heads are not aligned. Walk me through your approach.
What this is assessing: Cross-functional execution. Whether they can lead without authority. Whether they can align people who do not report to them.
Follow-up probes
- What would you do if one department head simply refused to engage?
- How do you track progress without becoming the bottleneck?
- What would tell you the initiative is not going to succeed?
Evidence that may indicate strength
- Starts by understanding each department head’s perspective
- Identifies the shared goal and the conflicting incentives
- Builds alignment before pushing for action
- Escalates to the CEO only if alignment genuinely cannot be reached
Points that may require further probing
- Uses the CEO’s name to force compliance
- Starts by pushing for action without understanding resistance
- Escalates immediately rather than trying to align
- Does not consider the department heads’ incentives
3. The CEO asks you to represent them in a meeting where you disagree with the position they want you to present. What do you do?
What this is assessing: Judgement and integrity. Whether they can represent the CEO faithfully while also being honest. Whether they understand the limits of proxy authority.
Follow-up probes
- Have you ever refused to represent a position — what happened?
- How do you capture dissent in the room without undermining the CEO?
- How do you follow up with the CEO afterwards?
Evidence that may indicate strength
- Presents the CEO’s position faithfully
- Flags their disagreement privately with the CEO beforehand
- Does not undermine the CEO in the meeting
- Captures feedback to bring back for the CEO to consider
Points that may require further probing
- Refuses to present a position they disagree with
- Undermines the position in the meeting
- Does not raise their disagreement with the CEO
- Treats the situation as binary: obey or undermine
4. How do you build trust with a leadership team that may be cautious about your proximity to the CEO?
What this is assessing: Whether they understand the legitimacy problem every Chief of Staff faces. Whether they can build credibility rather than relying on the CEO’s authority.
Follow-up probes
- Can you describe a specific moment when you knew trust had shifted?
- What do you do if one leader remains hostile regardless?
- How do you balance helping a leader with holding them accountable?
Evidence that may indicate strength
- Acknowledges the dynamic rather than pretending it does not exist
- Builds relationships individually before driving initiatives
- Is transparent about their role and does not gather intelligence covertly
- Demonstrates value by helping, not just monitoring
Points that may require further probing
- Dismisses the concern or claims it has not happened
- Relies on the CEO’s authority to establish credibility
- Does not recognise the tension between the role and the team
- Sees the team as obstacles to overcome
5. Tell me about a time you had to make a decision on behalf of the CEO when they were unavailable. How did you handle it?
What this is assessing: Proxy judgement. Whether they know when to act and when to wait. Whether they can make a decision that the CEO would support without being told what to do.
Follow-up probes
- How did you know the CEO would have supported your decision?
- What would you have done if the decision had gone wrong?
- How did the CEO react when you briefed them?
Evidence that may indicate strength
- Describes a specific situation with real stakes
- Understood the CEO’s thinking well enough to predict their position
- Made the decision and communicated it clearly
- Briefed the CEO promptly afterwards
Points that may require further probing
- Tended to wait for the CEO rather than acting
- Made a decision that surprised the CEO
- Cannot describe how they knew what the CEO would want
- Overstepped the authority they were given
6. What kind of CEO would you struggle to work with?
What this is assessing: Self-awareness and fit. Whether they understand what they need from the relationship. Whether they can be honest about a difficult question.
Follow-up probes
- Can you describe a time you adapted your style to a CEO who was different from what you expected?
- What would you do if you discovered the mismatch three months in?
- What does a great CEO–Chief of Staff relationship look like to you?
Evidence that may indicate strength
- Describes a working style, not a personality type
- Identifies what they need to be effective
- Is honest without being negative
- Shows they have thought about the two-way relationship
Points that may require further probing
- Cannot give a concrete example of building a working relationship with someone whose style differed from theirs
- Frames working relationships entirely in terms of personality fit rather than adapting to different operating styles
- Cannot describe what they need to be effective
- Frames it as the CEO needing to adapt to them
Practical scorecard
Score each competency separately and record concise evidence supporting your score. Do not allow one impressive answer to inflate unrelated competencies.
Scoring scale

|---|---|
| Strategic thinking and prioritisation Can they distinguish urgent from important? Do they help the CEO focus? | |
| Cross-functional execution Can they drive initiatives across functions? Do they hold people accountable without authority? | |

How to use this scorecard
- Score each competency separately.
- Record concise evidence supporting the score.
- Do not allow one impressive answer to inflate unrelated competencies.
- Do not average away a material role-critical concern.
- Discuss scores only after each interviewer has recorded their independent judgement.
- Use the scorecard to support — not replace — the final human decision.
How to run the debrief
Have each interviewer score independently before discussion. Focus the debrief on judgement, discretion and cross-functional credibility, as these predict whether the candidate will be trusted by the wider leadership team. The CEO’s view of the working relationship matters, but it should not override evidence about how the candidate will work with others. Distinguish between a candidate who demonstrated strategic thinking and one who is merely a capable project manager. Proxy judgement — how the candidate decides what the CEO would say or do — deserves careful scrutiny, as a Chief of Staff who misrepresents the CEO can create significant damage quickly.
Fairness and reasonable adjustments
Ask the same core questions of every candidate for this role. Use follow-up questions to clarify evidence rather than to catch candidates out. Make reasonable adjustments to format and timing where needed — for example, extra time, alternative formats, or breaks. Score evidence against the role requirements, not against your impression of the candidate's personality or communication style. Keep notes factual and job-relevant. Separate "not enough evidence" from "candidate lacks the skill" — the first may warrant a focused follow-up, the second is a scoring decision. The final hiring decision remains with the human hiring team.
Candidate experience: Explain the interview format at the beginning. Leave time for the candidate to ask questions. Avoid misleading candidates about the role or the team. Tell them what happens next and the expected timeline. Follow the agreed timing as closely as practical. Avoid repeatedly asking for information already covered in earlier stages.
Questions candidates may ask
Strong candidates will ask questions that reveal their priorities and how they think about the role. Be prepared to answer honestly — misleading a candidate about the role or the team risks a bad hire who leaves quickly.
- What is the CEO’s working style, and what do they most need from this role?
- How does the leadership team currently operate — are there established rhythms and processes?
- What strategic initiatives are underway, and where does this role fit?
- What authority does this role have to make decisions on the CEO’s behalf?
- How has the Chief of Staff role been defined previously, if at all?
Frequently asked questions
Is a Chief of Staff the same as an executive assistant?
No. An executive assistant manages the CEO’s schedule, travel and administrative tasks. A Chief of Staff drives strategic initiatives, prepares the leadership team and acts as the CEO’s partner on the business. The roles are different in seniority, scope and the skills required.
Should the CEO interview the candidate directly?
Yes, but not exclusively. The CEO should test the working relationship and thinking alignment. Other leaders should test cross-functional credibility and influence. A Chief of Staff who is only trusted by the CEO will struggle with the rest of the team.
What background makes a strong Chief of Staff?
There is no single path. Strategy consulting, operations leadership and startup generalist backgrounds are common. What matters more than background is judgement, adaptability and the ability to earn trust across the organisation.
How long should the process take?
Take the time to get this right. Include multiple conversations with the CEO in different settings: a structured interview, a working session on a real problem and an informal discussion. The working relationship is the most important thing to test.
