Accounting Interview Questions for Investment Banking: Core Prep Guide
Technicals
Accounting interview questions still eliminate candidates who memorised definitions but cannot explain cash versus profit. This guide builds the IB answers you need before three-statement practice.
If your broader technical base is shaky, start with the investment banking technical interview questions guide for valuation and M&A context. This article goes deep on one bucket: core accounting interview questions that appear in first-round screens, HireVue technical add-ons, and the warm-up before a three-statement scenario.
Candidates often know “assets equal liabilities plus equity” but collapse when asked why cash can rise while net income falls, or what happens to working capital when receivables spike. The fix is plain-English practice: every concept must have a cash story and a balance-sheet home.
What banks are really checking
Interviewers are not hiring you to be the firm’s accountant. They want evidence that you can:
- Explain profit versus cash without jargon fog
- Place common line items on the right statement
- Handle working capital and non-cash adjustments intuitively
- Adapt when the interviewer changes an assumption mid-answer
A candidate who sounds like they have built or reviewed models will explain why a line moves. A candidate who memorised flashcards will stumble on the first twist.
| What they ask | What they are really checking |
|---|---|
| “Walk me through the income statement” | Structure and judgement, not a shopping list |
| “What is working capital?” | Operating liquidity intuition |
| “How does depreciation affect the statements?” | Non-cash expense literacy |
| “Can cash go up if net income falls?” | Cash vs profit discipline |
| “What happens when AR increases?” | Working capital drag on cash |
The answer shape that survives follow-ups
Use this four-beat pattern for almost every accounting interview question:
- Define in one sentence a non-specialist could follow
- State the cash effect (or say there is none yet)
- Name the balance-sheet home
- Give a tiny example with round numbers
Example for depreciation:
“Depreciation spreads the cost of a long-lived asset over the periods that benefit from it. It reduces net income but is added back on the cash flow statement because it is non-cash. On the balance sheet, accumulated depreciation lowers net PP&E. If depreciation rises by 10 with a 25% tax rate, net income falls by 7.5, cash from operations rises by the add-back after tax effects, and net PP&E falls.”
That shape beats a long textbook paragraph every time.
Income statement questions you must own
Practise these until the answers are boring:
Walk me through the income statement. Revenue, then cost of goods sold to gross profit, then operating expenses to operating income / EBIT, then interest and tax to net income. Mention that banks care about both GAAP lines and adjusted views in models, but start with the clean walkthrough first.
Revenue versus cash collected. Revenue can be recognised before cash arrives (receivables) or after cash arrives (deferred revenue). Always separate recognition from collection.
COGS versus operating expenses. COGS tracks costs tied to delivering the product or service. OpEx covers selling, general, and administrative costs. Mixing them muddies margin analysis.
EBITDA versus net income. EBITDA is a rough operating cash proxy before interest, tax, depreciation, and amortisation. It is not cash. Say that out loud so you do not sound like a forum script.
Cash versus profit (the filter question)
“Can a company show positive net income and still run out of cash?” Yes. Growth in receivables and inventory, debt principal repayments, and heavy capex can absorb cash even when the income statement looks healthy.
“Can cash rise while net income falls?” Yes. Collecting old receivables, delaying payables, raising financing, or cutting capex can lift cash in a period when profits are weak.
Practise both answers with a one-line example. Interviewers love this pair because it separates memorisers from people who understand the statements.
Working capital questions
Working capital usually means current operating assets minus current operating liabilities (commonly receivables + inventory − payables, with variations by firm). Banks care because it explains cash timing.
| Change | Income statement | Cash effect (typical) |
|---|---|---|
| AR up | Revenue already recognised | Cash lower than profit |
| Inventory up | No immediate P&L if not sold | Cash tied up |
| AP up | Expense may already be in P&L | Cash conserved |
| Deferred revenue up | Revenue not yet recognised | Cash received early |
When asked “what is working capital?”, give the definition, then add one sentence on why bankers track it in diligence and models. Empty definitions fail.
Depreciation, capex, and PP&E
Know the triangle:
- Capex buys or builds long-lived assets (cash out on the cash flow statement; PP&E up)
- Depreciation allocates that cost over time (expense on the income statement; non-cash add-back on CFS; net PP&E down)
- Useful life and method change the pattern, but interviewers usually want straight-line intuition first
Follow-ups often include: “What if useful life doubles?” or “What if capex equals depreciation?” Practise those twists so you do not freeze.
Debt, interest, and equity basics
You do not need a full credit manual. You do need:
- Issuing debt: cash up, liabilities up; later interest expense and principal repayment
- Issuing equity: cash up, equity up; no mandatory interest
- Interest versus dividends: interest hits the income statement; dividends are a distribution of equity (not an expense)
If the interview moves into leverage or coverage, bridge to valuation with our DCF interview questions guide rather than inventing advanced credit theory you cannot defend.
How this connects to three-statement practice
Once definitions feel automatic, move to full walkthroughs:
- State the transaction
- Walk IS → CFS → BS
- Confirm the balance sheet still balances
- Invite the twist
Use our three statement interview questions guide for five core scenarios. Accounting interview questions are the vocabulary layer. Three-statement questions are the performance layer. Skipping either leaves a hole a superday interviewer will find.

A one-week practice plan
| Day | Focus |
|---|---|
| 1 | Income statement walkthrough + revenue vs cash |
| 2 | Cash vs profit pairs with examples |
| 3 | Working capital table until automatic |
| 4 | Depreciation / capex / PP&E with two twists |
| 5 | Debt vs equity basics + interest vs dividends |
| 6 | Mixed mock: five accounting questions, then one three-statement scenario |
| 7 | Light review of misses; sleep before interview day |
Record yourself once. If you hear yourself listing jargon without a cash sentence, rewrite the answer.
Mistakes that fail strong candidates
| Mistake | Fix |
|---|---|
| Textbook dump with no cash story | Add cash impact in sentence two |
| Treating EBITDA as cash | Say it is a proxy, then name real cash adjustments |
| Memorising one depreciation script | Practise tax-rate and useful-life twists |
| Skipping working capital | Drill AR, inventory, and AP with cash effects |
| Jumping to valuation before accounting is solid | Fix linkages first, then DCF and comps |
