Accounting Interview Questions
Accounting is the foundation of every investment banking interview. If you can't walk through the three financial statements and trace a transaction across all three, you won't make it past the first round. These questions test whether you truly understand how the income statement, balance sheet, and cash flow statement work — not just memorized the definitions. Check our IB Interview Prep Guide for the full picture.
The three financial statements
The income statement shows profitability over a period (revenue – expenses = net income). The balance sheet shows financial position at a point in time (assets = liabilities + equity). The cash flow statement reconciles net income to actual cash generated, adjusting for non-cash items and working capital changes. The three statements link through: net income flows to CFS and to retained earnings on BS; depreciation is expensed on IS and added back on CFS; capital expenditures reduce cash on CFS and increase PP&E on BS.
The depreciation question
If depreciation increases by $10: Income statement — pre-tax income falls $10, taxes fall $2.50 (at 25%), net income falls $7.50. Cash flow statement — net income down $7.50, but add back $10 depreciation (non-cash), so CFO increases $2.50. Balance sheet — PP&E down $10, cash up $2.50, so assets down $7.50. Retained earnings down $7.50. Balance sheet balances. Key insight: depreciation is a tax shield — the company saves $2.50 in taxes, which is why cash increases.
Working capital
Working capital = current assets – current liabilities. In IB interviews, the focus is on changes in net working capital (NWC) and how they affect cash flow. An increase in accounts receivable means revenue was recognized but cash wasn't collected — this is a use of cash (reduces CFO). An increase in accounts payable means expenses were incurred but not yet paid — this is a source of cash (increases CFO). An increase in inventory is a use of cash. Interviewers want to hear that you understand the cash flow implications, not just the formula.
Sample Interview Questions & Answers
QWalk me through the three financial statements.
The income statement shows revenue minus expenses to arrive at net income over a period. The balance sheet shows assets, liabilities, and equity at a point in time — assets must equal liabilities plus equity. The cash flow statement starts with net income and adjusts for non-cash items and working capital changes to show actual cash generated, broken into operating, investing, and financing activities.
QHow do the three statements link?
Net income from IS flows to the top of CFS and into retained earnings on BS. D&A is expensed on IS and added back on CFS. CapEx reduces cash on CFS and increases PP&E on BS. Debt issuance appears on CFS (financing) and increases liabilities on BS. The ending cash balance on CFS updates the cash line on BS.
QA company prepays $12M in rent. Walk me through the impact.
Day 1: No IS impact (not yet an expense). CFS: cash decreases $12M (operating outflow). BS: cash down $12M, prepaid assets up $12M — total assets unchanged. Over the next 12 months, $1M/month hits IS as rent expense, prepaid asset decreases $1M on BS, and the rent expense was already paid so no additional cash impact on CFS.
QWhat is the difference between accounts receivable and deferred revenue?
Accounts receivable: product/service delivered, cash not yet received (the customer owes you). It's an asset. Deferred revenue: cash received, product/service not yet delivered (you owe the customer). It's a liability. Both will resolve — AR when the customer pays, deferred revenue when you deliver.
Common Mistakes
- ✗Saying depreciation is a cash expense — it's non-cash, which is the entire point
- ✗Forgetting that the balance sheet must always balance after tracing a transaction
- ✗Not understanding the cash flow implications of working capital changes
- ✗Confusing deferred revenue (liability) with accounts receivable (asset)
Expert Tips
- Practice tracing 5–6 different transactions across all three statements until it's automatic
- Always start with the income statement, then cash flow statement, then balance sheet
- Say 'assuming a 25% tax rate' before any calculation — interviewers expect you to specify
- Know these cold: depreciation +$10, prepaid rent, inventory purchase, debt issuance, stock buyback

Accrual vs. Cash Accounting
Accrual accounting records revenues when earned and expenses when incurred, regardless of when cash changes hands. Cash accounting records transactions only when cash is received or paid. GAAP and IFRS require accrual accounting for publicly traded companies because it provides a more accurate picture of economic activity and financial position.
Questions to Ask the Interviewer
'Do you have any questions for me?' closes nearly every banking interview and is a real evaluation — it tests your genuine interest, your research, and your social judgment. The best questions are specific, can't be answered by the firm's website, and invite the interviewer to talk about their own experience, building rapport rather than extracting information.
