“Walk a £10m rise in depreciation through the three statements at a 20% tax rate.”
What they test. Accounting links.
Weak answer. Guessing the balance-sheet adjustments with no step-by-step flow.
Strong answer. Operating income down £10m, net income down £8m; CFO up £2m after the add-back; cash up £2m, PP&E down £10m, assets down £8m, matching retained earnings.
“Why might two firms in the same industry have very different WACC?”
What they test. Valuation theory and capital structure.
Weak answer. 'One is just run better.'
Strong answer. Different capital structures (debt tax shield), debt cost profiles or equity betas reflecting scale and revenue stability.
“Walk from EBITDA to unlevered free cash flow.”
What they test. Valuation mechanics.
Weak answer. Confusing unlevered and levered cash flows or missing working capital.
Strong answer. EBITDA less D&A to EBIT, tax on EBIT to NOPAT, add back D&A, subtract capex and adjust working capital.
“What are the primary return levers in an LBO?”
What they test. Financial engineering.
Weak answer. 'Buy low, sell high.'
Strong answer. Debt paydown from operating cash flow, EBITDA growth from operational improvement, and multiple expansion at exit.
“When is EV/Sales more appropriate than EV/EBITDA?”
What they test. Multiple selection.
Weak answer. Applying sales multiples randomly to healthy firms.
Strong answer. Early-stage or high-growth firms with negative or volatile EBITDA, where sales are a more reliable baseline.
