What is working capital (With Examples): Interview Answer Guide 2027

This working capital interview question is clearest with numbers. Imagine receivables rising $20 million as customers pay more slowly: revenue is recognized but the cash hasn't arrived, so operating cash flow comes in $20 million lighter. That increase in net working capital is subtracted in the free cash flow build — balance sheet timing made visible.

What This Working Capital Interview Question Tests

Working capital is current assets minus current liabilities — the short-term resources a business has available to fund its daily operations. In valuation and modeling, though, practitioners almost always mean operating (or net) working capital: accounts receivable plus inventory minus accounts payable, deliberately excluding cash and interest-bearing debt, which belong to financing rather than operations.

How to Answer This Working Capital Interview Question

Take a hypothetical distributor. At year-end, receivables rise $20 million as big customers negotiate longer payment terms, inventory rises $10 million ahead of a product launch, and payables rise $12 million as the company leans on suppliers. Net working capital increases by $20m + $10m − $12m = $18 million.

In the free cash flow build, that $18 million increase is subtracted: despite healthy reported profit, operating cash came in $18 million lighter because cash is now sitting with customers and on warehouse shelves, partly offset by supplier funding.

Common Mistakes on the Working Capital Interview Question

Including cash and debt. The textbook definition includes them, but operating working capital — what models use — excludes both. Using the broad definition in a free cash flow build double-counts financing.

Getting the sign wrong. An increase in receivables or inventory consumes cash (subtract); an increase in payables provides cash (add). Flipping these signs is the single most common modeling error.

Calling all working capital “good.” Rising working capital can signal growth — or deteriorating collections and obsolete inventory. Always ask what is driving the change.

This is the kind of technical question that commonly decides interview rounds — candidates report that one hesitant or rambling answer here can end the process on the spot. Practice saying your answer out loud until it sounds calm, structured, and confident.

FAQ

What is negative working capital, and is it bad?

Not necessarily — it often means customers pay faster than the company pays suppliers, so operations fund themselves. It is common in subscription and some retail models, though it can also signal distress if driven by stretched payables.

Why is cash excluded from operating working capital?

Because cash is a financing and treasury decision, not an operating one. Including it would mix how the business is funded with how it operates, defeating the metric's purpose.

How does working capital affect a DCF?

Through free cash flow: each year's change in net working capital adjusts operating cash flow. Companies with structurally rising working capital needs are worth less, all else equal, because more cash stays trapped in operations.

What is the cash conversion cycle?

The days inventory sits, plus days to collect receivables, minus days to pay suppliers — how long cash is tied up in operations. Shorter is generally better. Interview format may vary by role and region — check the official careers page for the current process.
