Try a question.
Say your answer out loud. Then open the walkthrough and see how your reasoning compares.
Depreciation increases by $10. Walk me through all three statements.
Assume a 25% tax rate, tax-deductible depreciation and no other changes.
Net income falls by $7.50. On the cash flow statement, add back the extra $10 of non-cash depreciation: cash rises by $2.50. On the balance sheet, cash is up $2.50 and net PP&E is down $10, so assets fall $7.50. Retained earnings also fall $7.50. The balance sheet balances.
Follow the cash tax saving, then check that both sides balance.
What is Callback AI?
Callback AI is a finance interview preparation app for iPhone and iPad. It brings together a study plan built around your interview date, technical practice across 14 areas, aptitude drills, mock interviews, an AI tutor and progress tracking.
Which interviews can I prepare for?
The curriculum covers investment banking and M&A, private equity, venture capital, restructuring and capital markets. It includes accounting, valuation, DCF, LBOs, fit and motivation, and the mental maths behind technical interviews.
Can I try Callback before subscribing?
Yes. You can download Callback and try a selection of introductory questions and practice drills. Pro adds the full curriculum, timed tests, mock rounds, the AI tutor, markets and the full study plan. Current subscription options are shown in the app before purchase.
What is a mock superday?
A superday is a series of interviews in one recruiting stage. Callback lets you rehearse a single interview or a sequence of interviewer seats, moving from junior to senior. Your result shows where your answers were strongest and what to practise next.
Does Callback work offline?
The bundled learning material works offline. Features such as the cloud AI tutor, market updates, account syncing and purchases need an internet connection. Spoken practice also depends on the capabilities and permissions of your device.
Is there an Android or web app?
Callback is currently available on iPhone and iPad through the Apple App Store. This website hosts the product information and interview preparation guides.
Will Callback guarantee an offer?
No app can guarantee an interview result or a job offer. Callback gives you a structured way to practise, find gaps and become more confident explaining your reasoning.
