Introduction
Almost every technical question in an investment banking interview is an accounting question underneath. Valuing a company starts from its financial statements, a leveraged buyout (LBO) model is a three-statement model with more debt, and a merger model is two sets of statements combined. Interviewers know this, so accounting is where they start, and it is the subject on which they are least forgiving: a candidate who cannot explain how depreciation reaches cash is unlikely to be trusted with a discounted cash flow.
What makes accounting questions useful to interviewers is that they have right answers and they reveal how someone thinks. A short question about a change in inventory shows whether a candidate understands that profit and cash differ, whether they can hold three statements in mind at once and whether they stay organized when the question has several steps. Those questions arrive at predictable points in the process, in a handful of recognizable forms, and the people asking them listen for the same few qualities.
Where Accounting Appears in the Process
The format varies by bank and by role, but most candidates for analyst and associate positions meet accounting at three or four points.
Screening and First Rounds
Many banks open with a recorded video interview, often on a platform such as HireVue, followed by a phone or video call with a banker. Recorded screens are mostly behavioral, but a short technical prompt, such as explaining the three statements, can appear, and the blog post on preparing for video interviews covers the format. Expect these screens to be closed-book: Goldman Sachs reminded applicants in 2025 that it prohibits external sources, including ChatGPT and Google search, during its interview process, as Fortune reported. First-round calls usually include a handful of standard technical questions, and accounting is the most reliable of them.
Superdays
The final round, usually several back-to-back interviews with bankers from analyst to managing director, normally includes at least one technical interview and technical questions scattered through the others. Here the questions become longer and connected: a transaction is described, then changed, then extended over two years. Senior bankers tend to ask fewer and broader questions, often testing judgment rather than mechanics. The blog's guide to preparing for a superday covers the day as a whole.
- Superday
The final round of investment banking recruiting, in which a candidate meets several bankers in back-to-back interviews on a single day, in person or by video. Offers are often decided within days of it, so it is where technical preparation is tested hardest.
Modeling Tests
Lateral candidates, associates and anyone interviewing with private equity firms after banking may face a timed modeling test, from a paper LBO done with a pen to a three-statement model built in Excel over several hours. These are accounting tests in practice: candidates often fail because their statements do not link or their balance sheet does not balance, the subject of accounting in modeling tests.
The Five Types of Accounting Question
Accounting questions fall into a small number of recurring types, and recognizing the type is the first step to answering well:
| Type | Typical form | What it tests |
|---|---|---|
| Definitional | What is goodwill? What is deferred revenue? | Precise knowledge of terms |
| Walkthrough | Walk me through the three statements | Structure and the links between statements |
| Transaction | What happens to the statements if depreciation rises by 10? | Mechanics, step by step |
| Multi-step | A company buys equipment with debt, then depreciates it and pays interest | Holding several effects at once |
| Judgment | Which statement would you use to evaluate a company, and why? | Understanding of what the numbers mean |
Definitional questions sound easy and are where careless candidates lose credibility, because a loose definition of something as basic as working capital or earnings before interest, taxes, depreciation and amortization (EBITDA) suggests the rest of their knowledge is loose too. Walkthrough questions test whether the candidate can explain a system in order, a skill covered in walking through the three statements.
Transaction questions are the core of most technical rounds, and they reward a fixed method more than speed, the approach set out in answering what-happens-if accounting questions. Multi-step questions are transaction questions joined together, often across years, and judgment questions ask the candidate to step back and explain why something matters.
What Interviewers Listen For
Most interviewers are not checking answers against a key. They are deciding whether they would trust the candidate with a model at two in the morning, and they listen for a few things.
Structure and Self-Correction
Structure comes first. A strong answer has an order, usually income statement, then cash flow statement, then balance sheet, and states each effect before moving on. A candidate who jumps between statements, even if every number is right, is hard to follow and hard to check. Accuracy matters, but it is judged together with self-correction: an interviewer will forgive a candidate who notices the balance sheet does not balance and finds the error far more readily than one who never checks.
Understanding Behind the Answer
The third quality is understanding. Interviewers often follow a correct answer with a simple "why?", why depreciation is added back, why deferred revenue is a liability, why a profitable company can run out of cash. A memorized answer fails that test; an answer built on the accounting equation and the links described in how the three statements link survives it.
Finally, interviewers notice how candidates handle what they do not know. Saying "I am not certain, but I would reason it through like this" and then reasoning from first principles is a good answer to a question beyond the candidate's preparation. Guessing confidently and being wrong is a poor one.
How the Bar Changes With Experience
Interviewers calibrate their questions to the candidate. Undergraduates applying for internships are expected to know the three statements, how they link and how common transactions flow through them, along with core definitions. Questions rarely go much beyond that, but they are expected to be answered cleanly, and candidates without a finance background can reach that level with a structured plan such as learning accounting for banking from zero.
Candidates from accounting backgrounds, such as audit or transaction services at a large accounting firm, face a higher bar on mechanics and a different test on judgment: interviewers want to see that they think about accounting as a banker does, in terms of value, cash and deal structure, rather than as a list of rules. Master of Business Administration (MBA) candidates fall between the two, with more focus on how accounting connects to valuation and deals.
Laterals and Associates
Lateral analysts and associates are expected to handle deal accounting: purchase price allocation, goodwill, deferred taxes created in acquisitions and the effects of financing structures, the topics covered in how an acquisition hits the three financial statements. For them, a slow or uncertain answer on a basic transaction is a serious warning sign, because they are expected to have done this work.
How to Prepare
The order of preparation matters more than its volume. Start with the statements themselves and how they link, then practice transactions until the method is automatic, then add multi-step scenarios, and only then move to the deal accounting that associate interviews require. Practicing aloud is essential, because answering an accounting question is a spoken skill as much as a technical one, and candidates who have only read answers often find they cannot say them in order.
Timing and Numbers
Answer length matters too. A walkthrough of the three statements should take about a minute, and a single transaction question well under that; answers that run longer usually lack structure rather than content. Interviewers also keep numbers simple, such as $10 of depreciation or a 25% or 40% tax rate, because they are testing logic, not arithmetic, so practice doing the arithmetic aloud until it is automatic and does not interrupt the explanation.
The questions most likely to come up are collected in the most common accounting interview questions, and the errors that cost candidates most often in common accounting mistakes in interviews. Accounting will rarely be the reason a candidate gets an offer, but it is very often the reason a candidate does not.
