Cash Flow Statement Interview Walkthrough for IB Recruits

"Walk me through the cash flow statement" is less common than the three-statement overview, but it shows up when interviewers want depth. You need the three sections, the NI bridge, and why cash can diverge from earnings. Lead with structure, then prove you know signs and section placement.

The short answer

"The cash flow statement explains the change in cash. It starts with net income, adjusts for non-cash items and working capital to get cash from operations, then shows investing cash flows like CapEx and acquisitions, then financing cash flows like debt draws, repayments, dividends, and equity issuance. The sum of CFO, CFI, and CFF equals the change in cash, which ties to the balance sheet."

The three sections

Δ Cash = CFO + CFI + CFF
Ending Cash = Beginning Cash + Δ Cash

Indirect method CFO (what banks use)

Most US corporates use the indirect method:

1. Start with net income
2. Add depreciation / amortization and other non-cash expenses
3. Subtract non-cash gains (or add losses) as needed
4. Adjust for changes in operating working capital

Memorize the sign rule cold. Most CFS misses in interviews are sign errors, not missing section names.

Worked mini bridge

Net income                        50
+ D&A                             20
− Increase in AR                 (10)
+ Increase in AP                   5
= CFO                             65
CapEx                            (30)
= Rough FCF-ish                   35

Exact free cash flow definitions vary; say which one you mean. "CFO minus CapEx" is a quick levered-ish shorthand, not identical to unlevered FCF used in DCFs.

Investing and financing intuition

LBOs care about CFO and CapEx for debt paydown capacity, and CFF for the debt schedule reality. If interest is inside NI, CFO is after interest in the typical indirect presentation: that matters when someone asks you to bridge to unlevered free cash flow.

How it links to the other statements

• NI comes from the income statement
• Changes in NWC and non-cash items reconcile to balance sheet movements
• Change in cash plugs the cash line on the balance sheet

If someone asks only for the CFS, still mention those ties once. Interviewers want to hear that you see one system, not three memorized lists.

Common interview traps

1. Treating CapEx as an operating outflow in CFO (it is investing)
2. Forgetting addbacks for D&A
3. Wrong NWC signs
4. Saying CFO must equal NI
5. Mixing CFO with unlevered FCF without defining interest and tax treatment
6. Putting dividends in CFO because "they feel operating"

Unlevered FCF sidebar

Interview quick form:

UFCF ≈ EBIT(1 − t) + D&A − CapEx − ΔNWC

That is not identical to CFO minus CapEx when interest sits inside NI. Say so if they press. Banks live in both languages: CFS for historical articulation, UFCF for DCF valuation.

Direct vs indirect (keep it short)

If someone asks about the direct method, say it lists operating cash receipts and payments explicitly, while the indirect method starts from NI. US interviews almost always expect the indirect walk. Do not spend half your answer comparing formats unless they ask.

Quality of earnings angle

High NI with weak CFO is a yellow flag: aggressive revenue recognition, inventory build, or AR stretch. Strong CFO with weak NI can reflect D&A-heavy businesses or working capital release. You do not need a full quality-of-earnings speech, but naming the NI-to-cash bridge as a diligence lens scores points.

30-second verbal

"Cash flow statement has operations, investing, and financing. Operations bridge net income to cash using non-cash addbacks and working capital. Investing is CapEx and M&A. Financing is debt and equity cash flows. Together they equal the change in cash on the balance sheet, which is why cash can diverge from earnings even when the statements link."

Practice ladder

1. Full CFS walk
2. Depreciation +10
3. AR +10
4. Inventory +10
5. Bridge CFS language to Unlevered vs Levered FCF
