The Assessment Centre Case Study
A pack, a clock, and a decision to write down. It is the closest the day comes to the job, and it is scored on the three things a credit desk scores: the order you read in, the number you found, and whether you decided.
BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED
// THE SHORT ANSWER
The case exercise at a banking assessment centre is a pack — a company description, a set of financials, a request — with a task in three parts: the risks you see, the questions for management, and whether you would lend and how. It tests whether you read in the lender's order, find the number the decision rests on, and decide inside the time. Read the ask first, then the file, and write the recommendation before anything else — one line, three reasons, two conditions, the fact that would reverse it — keeping a third of the time for writing.
BASIS Practitioner judgment from sixteen years in commercial banking, set out in How Bankers Think (Highbank Press, 2026). Every borrower on this site is a composite constructed for teaching, not a client. The market is mid-market commercial lending as practised in New Zealand and Australia; where a convention differs elsewhere, the page says so.
// PRACTISE THE ROUND
Five questions commercial banking panels genuinely ask, with the senior interviewer's read on every answer — a quiz that tests judgment, not recall.
// 01 — WHAT THE DAY IS
For graduate and early-career programmes in this market the process usually runs in four stages — online assessments, a recorded video interview, the assessment centre, and final interviews with the desk — and the interview hub sets out all four. The assessment centre is the third: half a day or a day with several candidates, a behavioural interview, an individual case built on a set of financials, a group exercise, and sometimes a short presentation or a numerical test. The earlier stages screen for structure and motivation; the case is the part that decides the later ones, because it is the first time the bank sees you do the job.
// 02 — THE PACK, AND WHAT IT IS REALLY TESTING
The pack is a company description, a set of financials — usually two or three years, sometimes a forecast — and a request or a scenario: a larger facility, an acquisition, a season that did not clear. The task at the end is usually in three parts: the risks you see, the questions you would put to management, and whether you would lend and on what terms. Some banks want it written, some presented, some both.
It is not testing accounting. Everyone in the room has enough. It is testing whether you read in an order rather than wherever your eye lands, whether you find the number the decision rests on, and whether you decide — with reasons a desk would recognise, inside the time. Those are the three things a credit analyst is scored on for the whole of the first year, which is why the case is the closest the day comes to the job and why the panel weights it as it does.
// 03 — HOW TO ATTACK IT IN THE TIME
Then the file, in the lender's order · what grew and what it is made of · whether the earnings became cash · whether the request matches the need · only then the way out
Find the one number · the thing the decision rests on: cash against debt, a customer's share, a cycle that lengthened
Write the recommendation first · one line, three reasons, two conditions, the fact that would reverse it
Then the risks and the questions · in the order they bear on the decision, each question with what you expect the answer to show
Keep a third of the time for writing · a reading with nothing on paper scores as nothing
The order matters more than anything else on this page. Candidates who read the statements in the order they are printed spend their time on the profit line, which a lender trusts least, and reach the question that decides most files — did the profit become cash? — with no time left to answer it. Credit Analysis for Beginners is that reading order in full, and Cash Flow Analysis is why it starts where it starts. Do not invent facts the pack does not give you; say what you would want to know and what you expect it to show, which is the question-to-management task answered properly.
// 04 — THE WRITTEN ANSWER
Write it in the shape of a credit paper, shrunk to a page. The answer goes first — lend, decline, or lend on conditions, in one sentence. The numbers go in sentences, not in a table you leave the assessor to interpret: revenue grew, operating cash flow turned negative, debtor days lengthened from this to that. The risks are stated with what is left after them, not as a list. The conditions each answer a named risk, and a list of things you would like to see is read as a way of not deciding. And the one fact that would reverse your view goes at the end, because it tells the assessor you know what your recommendation rests on. How to Write a Credit Paper is the full form, with one complete paper on a published file; the assessment-centre version is the same structure at a tenth of the length.
// 05 — THE PRESENTATION
Where the case is presented, it is presented in ninety seconds whether or not you are given longer, because the panel stops listening for the call after that and starts listening for whether you can defend it. The Case Walkthrough is the method: five sentences, the answer first, and the curveball the panel will throw — a fact they add after you finish, to see whether your view moves for a reason or holds out of pride. Rehearse it aloud on a file before the day; the difference between a walkthrough you have said and one you have only read is audible.
// 06 — THE GROUP EXERCISE
The same test run in public. A pack, a group, a decision to reach together, and assessors at the edge of the room marking the person who moved the group's answer with a reason — not the person who spoke most. What scores: structuring a discussion that has none, in the first minute; holding a view against the room when the evidence supports it and changing it when the evidence changes; keeping the group to the time; and asking the candidate who has not spoken what they think, which assessors notice every time. What loses: dominating, silence, and agreeing with whoever spoke last. The reading order that wins the written case wins the table too — the candidate who says “before we argue about the margin, has anyone looked at the cash flow?” has usually already been marked.
// 07 — THE MISTAKES THAT LOSE IT
Summarising the pack. A description of the company back to the people who wrote it, with no decision — the commonest answer and the lowest scoring. Deciding nothing. “I would want more information before forming a view” is a sentence, not an answer; the panel wants the information named and the view given subject to it. Running out of time with the reading done and nothing written. Ignoring the ask — answering whether the business is good when the task asked whether to lend the amount requested. Inventing facts the pack does not contain. Every ratio, no number. A page of ratios is not a reading; the assessor wants the one that decided it. Treating the numerical test as the test. It screens; the case decides.
// 08 — HOW TO PREPARE IN A WEEK
Make decisions on real-shaped files, not notes about them. The nine published files on this site are each a company, its numbers and a request, with a call to commit to before the senior read opens — the assessment-centre exercise, run nine times. Read Issue 04 and Issue 01 together: the same request, a yes and a no, and the reason for each. Take the quiz for the temperament the behavioural interview scores. Say the ninety seconds aloud on two files. And read the seven-days section of the interview hub for the rest of the day. The free sample case below is one whole case worked to exactly the shape the exercise wants, with the interviewer's read of it.
// QUESTIONS PEOPLE ASK
- What is an assessment centre in banking?
- The stage of a graduate or early-career process where the bank sees several candidates at once, over half a day or a day, and scores them on tasks rather than on conversation: a behavioural interview, an individual case built on a set of financials, a group exercise, and sometimes a short presentation or a numerical test. It usually follows online assessments and a recorded video interview, and precedes final interviews with the desk. The case is the part that decides the later stages, because it is the closest the day comes to the job.
- What is the case study at a banking assessment centre?
- A pack — a company description, a set of financials, and a request or a scenario — with time to read it and a task at the end, usually in three parts: the risks you see, the questions you would put to management, and whether you would lend and on what terms. It is not testing accounting knowledge; every candidate in the room has enough. It is testing whether you read in an order, whether you find the number the decision rests on, and whether you decide — in writing, or out loud, or both — with reasons a credit desk would recognise.
- How do you prepare for a graduate banking case study?
- By making decisions on real-shaped files, not by reading about them. Read a company in the lender's order — what grew and what the growth is made of, whether the earnings became cash, whether the request matches what the business needs — until it is a habit; practise finding the one number a decision rests on; and rehearse the shape of an answer: one line, three reasons, two conditions, the fact that would reverse it. The nine published files on this site are that practice, free, each with a call to commit to before the senior read; the free sample case is one whole case worked to exactly the assessment-centre shape.
- What are assessors looking for in the group exercise?
- The person who moved the group's answer with a reason — not the person who spoke most. Assessors mark whether you can structure a discussion that has none, hold a view against the room when the evidence supports it, change it when the evidence changes, keep the group to the time, and bring in the candidate who has not spoken. Dominating the room scores badly; so does silence. The exercise is the case question run in public, and the same reading order that wins the written case wins the table.
- How long is the case, and do I need to know accounting?
- Banks differ; the individual case is typically under an hour including the writing, and the group exercise shorter. You need enough accounting to read three statements and know how they connect — what a graduate in commerce or finance already has, and what a determined candidate from another discipline can build in a few weeks with the beginners' guide on this site. You do not need to spread the accounts to audit standard, calculate every ratio, or know any bank's policy. You need to read in order, find the number, and decide.
