Assessing a Senior Appointment: Why the Interview Problem Is Worse at the Top
There is an odd inversion in how organisations hire. The decisions that cost the most to get wrong are made with the least direct evidence. A customer service applicant might be tested, screened and observed before anyone commits. A finance director is appointed on a CV, a shortlist assembled by a search firm, three conversations and two references chosen by the candidate. The more the appointment matters, the more the process leans on the instruments that predict least, and the people running it are usually the ones least exposed to the consequences.
This piece is about why that happens, what it costs, and what a senior assessment looks like when it is built to produce evidence rather than reassurance. It assumes the general case is already made; why interviews do not predict job performance covers that. The argument here is that every weakness in the ordinary interview is amplified at senior level, and a few new ones appear.
The instruments get weaker as the stakes rise
Track record
At junior level, a track record is mostly the person's own work. At senior level it is the work of a team, in a market, at a moment. A commercial director whose region grew fast may have been excellent, or may have inherited a good team in a rising market with a product that sold itself. Separating the individual from the conditions is close to impossible from the outside, and the candidate has every reason to present the results as their own. The higher the role, the more the CV describes outcomes the candidate did not personally produce.
References
References are chosen by the candidate, which at any level limits what they can tell you. At senior level the referees are often peers, former board colleagues or people who owe the candidate something, and many employers now give factual references only, confirming dates and title and nothing else. What survives is a set of warm, unspecific endorsements from people selected for their warmth. A reference that would change your mind is precisely the one you will not be given.
The interview itself
Senior candidates have been interviewed more often than anyone else in the building, have been coached, and have spent a career learning to hold a room. Every quality the unstructured interview rewards, confidence, fluency, composure in conversation, presence, is one a senior candidate has had decades to polish, and none of it is the job. A board that comes out of an interview impressed has learned that the candidate is impressive in interviews. It has learned almost nothing about how the person decides when the information is incomplete, the stakeholders disagree and the cost of delay is real.
The shortlist
A search firm's shortlist arrives pre-filtered by network and by narrative: who the firm knows, who is known to be available, and whose story is easiest to sell. That is a service, and a legitimate one, but it means the candidates in front of you were selected on the same weak signals before you ever met them. The firm is also paid on placement, which is not a reason to distrust it, but it is a reason not to treat the shortlist as evidence of suitability.
The resemblance trap, with a board attached
The finding that managers hire people who remind them of themselves is a decade old and holds at every level. At the top it has a particular shape: boards are drawn from a narrow pool, senior candidates often come from the same pool, and the interview becomes a recognition exercise. The candidate who sounds like the board is not the candidate who will do the job best. They are the candidate who is easiest to appoint.
What a wrong senior appointment costs, and why it is found late
The salary is the smallest part. A senior hire makes decisions from the first week, and a poor one makes poor decisions with the organisation's money and people for as long as they are there. The good people under them start to leave before anyone senior has admitted there is a problem. The strategy they were hired to deliver stalls, and the eventual exit comes with a settlement, a gap and a second search. The real cost of a bad hire sets out the components; at senior level every one of them is larger and several are hard to reverse.
The problem is compounded by how late it is recognised. A senior appointee controls much of the information that flows upward about their own performance. The board sees the reports the person chooses to write, hears the version of events the person chooses to tell, and has fewer independent sources than a line manager has about a junior. Doubts form slowly and are voiced later still, because admitting a senior mis-hire means admitting the process that produced it was inadequate, and the people who ran that process are the ones who would have to say so.
From January 2027, the ordinary unfair dismissal qualifying period in Great Britain falls from two years to six months, and the cap on compensatory awards is removed. Existing protections for automatically unfair dismissal and discrimination are unchanged. For senior appointments this matters in two ways at once. The window to identify and address a poor appointment is shorter, at the level where problems are recognised slowest. And the removal of the cap bites hardest at exactly the salaries where a senior dismissal is most likely to be contested. How to prepare for the six-month threshold covers the general case; the senior case is the one where the evidence behind the original appointment is most likely to be examined.
The one work-sample tradition at the top, and why most employers never get it
There is one part of the market that has always assessed senior candidates on what they do rather than what they say: the executive assessment centre, run by occupational psychologists, with simulations, in-tray exercises, role-played stakeholder meetings and trained observers. The research behind it is strong and it remains the norm for the largest employers and the public sector. It is also expensive, slow to arrange and dependent on specialist assessors, which is why the overwhelming majority of senior appointments in the UK never get one. Most organisations settle for the interview-plus-presentation, and a presentation is a prepared performance on a topic the candidate chose how to frame. It measures preparation, which senior candidates have in abundance.
The constraint was never the idea. The idea, put the candidate in front of the actual decisions the job contains and see what they do, is the right one and has been since the research settled it. The constraint was the cost of building role-specific scenarios and of having someone qualified read and score every response. That constraint has changed, which is what makes a proper senior assessment available to organisations that could never have run an assessment centre.
What to assess a senior candidate on
Not knowledge. Anyone on a credible senior shortlist knows the domain, and knowledge has a right answer, which is exactly what a senior role does not offer. The things that separate senior candidates are visible only in decisions with no clean answer.
Judgement under ambiguity, with stakes: what they do when the information is incomplete and waiting has a cost. Stakeholder reasoning: whether they can hold the board, a peer, a regulator, a major customer and their own team in view at once, and whether they notice the one they are neglecting. Prioritisation across strategic demands that genuinely compete, where the honest answer involves telling someone senior no. Ownership, which shows in the language: whether the candidate's account of a hard outcome is about what they decided or about what the market did. Composure when challenged by an equal rather than a subordinate. And what they choose not to do, which at senior level is often the more revealing half of the decision.
None of that can be reliably extracted from a conversation about the past. All of it is visible in a realistic scenario about the future of this role, if the scenario is built to contain those pressures.
How to build a senior assessment that works
1. Build the scenarios from the first year of the actual job
Every senior role has a handful of decisions waiting for whoever takes it: the budget the board is about to cut, the underperforming direct report the last incumbent never dealt with, the customer threatening to leave, the regulator's letter, the peer who wants the same resources. Write those down. They are the assessment. A scenario built from a competency framework tests the framework; a scenario built from the job tests the job.
2. Make the candidate produce, not recognise
Give them the situation and ask what they would do, in what order, and why, in their own words. No options to choose between and no right answer to find. A senior candidate can spot the defensible option in any multiple-choice list; asking them to construct and justify a course of action is a different task, and it is the task the role consists of.
3. Give it the time the decision deserves
A senior scenario needs room: several stakeholders, a constraint that bites, a piece of information that arrives late. Sixty to ninety minutes across a small number of extended scenarios is proportionate for an appointment that will take years to unwind if it goes wrong, and it is what the candidate should expect. Serious people are not put off by a serious exercise. They are put off by a ten-minute quiz that signals the organisation has not thought about the role.
4. Score in the context of the seniority
A response that would be excellent from a team leader is merely adequate from a director. The scoring has to be calibrated to the level and to the specific demands of this role, or a fluent generalist outscores the candidate who actually engaged with the hard part of the problem.
5. Same scenarios for every finalist, interview afterwards
Consistency is what makes the results comparable and the process defensible, and it answers the equity objection before it is raised: no finalist is singled out because every finalist does the same thing. Then hold the board interview with the assessment in hand. Its job changes from forming an impression to testing what the assessment surfaced: the candidate who deferred the difficult conversation with the peer, or committed resources before checking the constraint, gets asked about that, with the specifics in front of everyone.
6. Keep the record
The scenarios, the responses, the scores and the reasoning, for every finalist. Of all the appointments an organisation makes, the senior one is the most likely to have its basis examined later, by a tribunal, an auditor, a successor board or the finalist who was not chosen. The record is what lets you show the decision was made on evidence about the role, and it is the one part of the process that cannot be reconstructed afterwards.
The objections, and what they are really saying
"Senior candidates will not do assessments." Some will not, and that is information. A candidate who declines to engage with the real problems of the role they are asking to lead has told you something about how they will engage with them once appointed. Framed properly, as the first-year decisions of this job rather than a test, most serious candidates treat it as the first interesting part of the process.
"We know them, they came recommended." This is the resemblance trap in its most respectable clothing. Being known is not evidence of suitability for this role, and a recommendation is a reference with the formality removed.
"The board interview is the assessment." It is an interview, conducted by people who are expert in their own fields and not in selection, with a candidate who is expert in interviews. Everything above applies to it. It is a valuable conversation to have after the evidence is in, and a poor way to generate the evidence.
Where PRODICTA fits
PRODICTA's senior appointment assessment is the extended depth of the same method described in what is an employee suitability assessment?: 60 to 90 minutes, multiple work scenarios built from the role details you provide, probing stakeholder reasoning and strategic decision making, and the fullest report PRODICTA produces. Scoring is calibrated to the seniority set out in the role, every strength and watch-out is anchored to a direct quote from the candidate, and the report carries the interview questions to take into the board conversation. It is one input to the decision, not the decision. If you are weighing it against other approaches, how to choose a pre-employment assessment tool gives the questions to ask, and how it works covers the steps from role details to report.
