Walk me through the three financial statements

This is usually the first technical question in a banking interview, and often the first one anyone asks a student. It looks basic, which is exactly why getting it wrong is fatal — if you cannot explain how the three statements link together, nothing else you say about valuation or modelling will be believed.

The three statements are the income statement (did the company make a profit?), the balance sheet (what does it own and owe?), and the cash flow statement (where did the cash actually go?). The interviewer wants to hear that you understand these as one connected system, not three separate reports.

Signpost first. Say what the three statements are and what each one does, in one sentence, before you explain how they connect. That gives the interviewer a frame.

The income statement shows revenue, costs and profit over a period — a quarter or a year. It ends with net income. The important thing to say is that net income is an accounting measure, not cash: it includes non-cash items like depreciation and excludes things like capital expenditure.

The balance sheet is a snapshot at a single point in time. Assets on one side; liabilities and shareholders' equity on the other. It must balance, because everything the company owns was funded either by borrowing or by shareholders.

The cash flow statement bridges the two. It starts from net income and adjusts it back to actual cash, split across three sections: operating, investing and financing.

Then explain the links — this is the part being tested.

Start with net income. It flows from the bottom of the income statement to the top of the cash flow statement, and it also flows into retained earnings on the balance sheet.

From net income, you add back non-cash charges like depreciation, because they reduced profit but no cash left the business. You then adjust for changes in working capital — if receivables go up, you booked revenue but haven't been paid, so cash is lower than profit suggests.

That gives cash from operations. Subtract capital expenditure to get to investing, then add or subtract debt and equity movements for financing.

The three sections sum to the net change in cash for the period. That number lands in the cash line at the top of the balance sheet, and the balance sheet balances again.

The standard follow-up: "Depreciation increases by $10. Walk me through all three statements." Assume a 25% tax rate.

• Income statement: operating income falls $10, net income falls $7.50.
• Cash flow statement: start with net income down $7.50, add back the $10 of depreciation — cash is actually up $2.50.
• Balance sheet: cash up $2.50, PP&E down $10 — assets fall $7.50. Retained earnings fall $7.50. It balances.

Practise saying that out loud until it is automatic. It comes up constantly.

Do you understand accounting or just vocabulary? Anyone can name the three statements. Only someone who understands them can explain why depreciation increases cash.

Can you keep track of several moving parts? The linkage question requires holding three statements in your head at once and updating each correctly.

Are you precise? Small errors here — forgetting tax, getting the sign wrong — are noticed immediately, because this is the one question every interviewer knows cold.

Listing the statements without linking them. The question is about how they connect. Describing each in isolation answers a different question.

Forgetting tax in the depreciation walkthrough. The most common error by a wide margin. Depreciation is tax-deductible, so the hit to net income is the after-tax amount.

Saying net income equals cash. It doesn't, and the whole point of the cash flow statement is explaining the gap.

Getting the working capital direction wrong. An increase in receivables or inventory uses cash. An increase in payables provides cash. Get this backwards and it undermines everything else.

Rushing because it feels easy. It is a basic question, which is why sloppiness on it is so damaging.
