Accounting interview questions
The three statements, how they link, and the depreciation walk-through that every banking interview eventually arrives at.
Accounting is the foundation layer. If you cannot link the three statements, every valuation answer you give afterwards rests on sand — and interviewers know it, which is why this comes first.
Walk me through the three financial statements
The answer
“The income statement shows profitability over a period: revenue down through costs to net income.
The balance sheet is a snapshot at a point in time: assets on one side, liabilities and equity on the other, and it must balance.
The cash flow statement reconciles net income to the actual cash that moved, split into operating, investing and financing activities.
The reason all three exist is that profit and cash are not the same thing. A company can be profitable and run out of money.”
How do the three statements link?
This is the follow-up, and it is the one that separates people.
- Net income from the bottom of the income statement is the top line of the cash flow statement, and it flows into retained earnings on the balance sheet.
- The cash balance at the bottom of the cash flow statement is the cash line at the top of the balance sheet.
- Non-cash charges like depreciation reduce income-statement profit but are added back on the cash flow statement, because no cash left the business. The same depreciation reduces the carrying value of PP&E on the balance sheet.
If depreciation increases by $10, what happens?
The single most-asked accounting question in banking. Assume a 25% tax rate and work through all three statements, out loud, in this order.
The walk-through
Income statement: operating income falls by $10. At a 25% tax rate, net income falls by $7.50.
Cash flow statement: start with net income down $7.50, then add back the $10 of depreciation because it is non-cash. Net effect: cash increases by $2.50 — the tax saved.
Balance sheet: cash is up $2.50, PP&E is down $10, so assets fall by $7.50. On the other side, retained earnings fall by $7.50 through net income. It balances.”
The insight worth stating explicitly: a larger non-cash charge increases cash, because it reduces the tax bill without costing anything. That is the whole point of the question.
Other questions that come up constantly
Which statement would you pick if you could only have one?
The cash flow statement. It is the hardest to manipulate, and it tells you whether the business actually generates money. A defensible alternative is the balance sheet — two balance sheets let you derive much of the rest — but have a reason ready either way.
What is working capital and why does a change in it matter?
Current assets minus current liabilities. An increase in working capital — more inventory, more receivables — consumes cash, because you have paid for something you have not yet been paid for. Fast-growing companies often have strong profits and negative cash flow for exactly this reason.
How can a profitable company go bankrupt?
By running out of cash. Profit is an accounting measure that recognises revenue when earned, not when collected. A business with long receivables, heavy inventory or a large debt repayment falling due can be comfortably profitable on paper and still fail to meet an obligation. This is why the cash flow statement exists.
What is the difference between accrual and cash accounting?
Accrual recognises revenue when it is earned and costs when they are incurred, regardless of when cash moves. Cash accounting records only cash in and out. Public companies use accrual because it matches revenue to the costs that produced it — which is also precisely why the cash flow statement is needed to translate back.
