The 100-Day Plan in a Senior Interview: What a Board Wants to See

A 100 day plan is the question a chair asks when a candidate is close to an offer, and the board is not buying the plan. It is listening to how you think about a business you have only seen from outside. JOH Partners, which has closed more than 1,000 senior mandates since 2014, sees the same pattern at this stage. Candidates who arrive with a tidy 30-60-90 slide tend to lose ground, and candidates who say plainly what they do not yet know tend to gain it. This guide is for chief executive, chief financial officer and other C-suite finalists who expect to be asked for their first 100 days. It covers what the board is testing, why the standard template reads as junior, and how to answer.

It sits with the other board-level interview guides. The format of a formal presentation round is covered in the executive interview presentation. This guide is about the content of the plan itself.

What is a board really asking when it asks for a 100 day plan?

Three things, none of which is on the surface. First, can this person think clearly about a business they do not yet understand? Second, will they act too early? Third, will they tell us what they find, including when it is uncomfortable?

The directors in the room have usually appointed several leaders. They know that no plan written from outside survives contact with the business. What they cannot easily judge is the candidate's habits: whether you reach for a solution or a question, and whether you can hold off on a decision until you have enough to make a good one.

That is why a strong answer is often shorter than a weak one. The candidate who speaks for twelve minutes about workstreams has told the board how well they can organise. The candidate who speaks for four minutes about what they would find out first has told the board how they would behave.

Why does the 30-60-90 template read as junior at board level?

Because it assumes the work is already known. A 30-60-90 plan works for a role with a defined job: learn the systems in month one, take on accounts in month two, own a target in month three. Each stage is a task someone else has already set.

At the top of a company, nobody has set the tasks. The first job is finding out what the tasks are. A chief executive who tells the board that by day 60 they will have a new operating model is saying they have decided the answer before they have seen the question. The directors hear a person who has used a template, not a person who has run a business.

The template also hides risk. A neat grid of dates and deliverables gives the board nothing to push on. A chair wants to test your reasoning, and a smooth plan offers no handle. If you must use a structure, keep it loose: what you will learn, what you will decide, what you will leave alone. Three headings do more work than three columns of dates.

What should you say you cannot know from outside?

This is the part most candidates skip, and it is the part boards remember.

Write down, before the interview, the five or six things you cannot know yet. The real state of the order book. Whether the finance team's numbers can be trusted. Which of the senior team the chair would keep if asked in private. What was promised to a lender or a major shareholder that is not in the board papers. Whether the strategy in the information memorandum is the strategy the business actually follows.

Then say them. Not as a list of anxieties, but as the start of your plan: "Before I commit to anything I would want to know four things, and I would ask these people." A board hears confidence in that. It hears a person who knows where the blind spots are and has a way to close them.

A board does not need you to know the answer on day one. It needs to hear that you know what you do not yet know, and how you would find out.

How do you show that you will listen before you act?

Be specific about who. "Stakeholder engagement" is not an answer. A chair wants names and roles: the chief financial officer on day one, because every number you will be shown passes through that office; the two or three people running the largest operating units; the head of risk or internal audit; the lead lender; the five largest customers; and, in a family-owned company, the family member who sits on the board and the adviser the family trusts.

Say what you would ask. A short list helps. What would you change if you were me? What have you tried that did not work? What am I not being told? The point of these questions is not the answers alone. It is that you can be seen to ask them, because the leadership team will judge you on the first month and so will the board.

There is a second reason to be specific. Boards compare candidates. When three finalists talk about "listening tours" and one says "I would spend the first week with the finance team before I met anyone else, because I would want to see the numbers without anyone's commentary", that is the answer the chair remembers in the debrief.

What will you deliberately not do in the first 100 days?

This is the question that separates experienced leaders from capable ones. Anyone can list what they will do. Few say what they will hold back.

Pick two or three. You will not restructure the top team before you have seen each person work. You will not announce a new strategy until you have tested the old one against the numbers. You will not make a large commitment, such as an acquisition or a major hire, that you cannot reverse. And you will not change the things that are working, however much they offend your taste.

Give the reason in one sentence each. "I would not change the reporting lines in the first quarter, because I would not know yet which of them are doing the work and which are just the way things have always been done."

Tell the chair one thing you will leave alone in your first 100 days. It shows you have run a business before.

The same discipline appears in what boards ask of chairs. The chair onboarding playbook sets out how a new chair should use the first 100 days, and a candidate for chief executive who has read it will understand what the chair is also trying to do in the same window. For what boards watch for when a first 100 days goes wrong, JOH's perspective on the ninety-day signal lists the early signs.

What does a family-group chair in the Gulf listen for?

In a group holding controlled by a family, the audience for your first 100 days is wider than the board. The founder and the founder's children will be watching. So will the managers who have been there for thirty years, and who have seen several outside chief executives arrive with big ideas and leave without having used them.

A chair in that setting is listening for three things. Whether you will respect what built the business before you change it. Whether you will be straight with the family when something is wrong. And whether you understand that your authority is lent to you and has to be earned in small, visible ways before it can be used in large ones.

JOH's engagement placing the first non-family chief executive into a Saudi industrial group is a reminder of what that handover involves. When an outsider takes over a business run by its founders, the first 100 days are read closely by everyone, and a candidate who has thought about that will answer differently from one who has not.

How should you deliver the answer in the room?

Keep it spoken. If the chair asks the question in conversation, answer in conversation. Take two or three minutes, name the five or six things you need to find out, say who you would speak to, and finish with the two things you would leave alone. Then stop, and ask the chair what they think you have missed.

That last question matters. A chair who is invited to add to your plan becomes a partner in it, and the answers tell you what the board is worried about. If the chair says "you have not mentioned the regulator", you now know what to prepare for the next round.

If you are asked for a written plan or a presentation, keep it to a few pages and label it a first view. The boundary with the format round is covered in the executive interview presentation. If the vacancy is an interim appointment, the answer changes again: the mandate is shorter and the test is what you leave for your successor, which is the subject of the interim CEO interview. For the permanent top job, the CEO interview covers what the board is deciding across the whole process.

How do you prepare when the plan has to come from you?

Start by writing the answer in four sentences. One on what you need to learn. One on who you will learn it from. One on what you will decide once you have. One on what you will leave alone. If you cannot say it in four sentences, you are not ready to say it in four minutes.

Then test it on someone who will push back. A former colleague, a chair you trust, or an executive search partner who has sat in the room. The aim is to find the weak sentence while it is cheap to fix.
