Investment Banking Interview Prep

Everything you need to prepare for investment banking interviews in 2026. Technical questions, behavioral frameworks, networking strategies, and practice methods.

WORK THROUGH THE DECISION

Diagnose the first broken link in your answer

Choose your next preparation task from an observed failure. Repeating a question bank is inefficient when you have not identified whether the problem is recall, mechanics, assumptions or explanation.

Run a four-part diagnostic

TestPromptPassing evidence
DefineWhat does enterprise value represent?Clear distinction from equity value
CalculateIssue $100 of debt at parCash and debt rise; initial earnings do not
ChallengeWhat changes after cash interest is paid?Explicit timing and tax assumptions
ExplainWhy does the balance sheet still balance?Reconciliation, not just a memorized direction

Use the full debt-issuance exercise for the calculation. Record the first point at which your answer breaks. If you miss the definition, do not begin with an advanced merger model. If the arithmetic works but the explanation fails, practice speaking through a small example.

Build an error log that changes tomorrow’s session

For each miss, record the original question, your wrong assumption, the corrected reasoning and one changed-input follow-up. A useful correction is “I treated issuance proceeds as revenue; they are financing,” not “study accounting harder.”

Try the same question without notes later. Then change one assumption. For example, replace cash interest with PIK or remove the immediate tax benefit. This distinguishes understanding from recognition. No fixed number of study hours guarantees readiness.

Match the resource to the problem

Use free material first when you need one concept: accounting mechanics, DCF assumptions, or behavioral story selection. The technical PDF fits a need for organized self-study across several technical topics; it is not the right purchase for a purely behavioral issue or a broken application process.

The SEC’s financial-statement guide supports the accounting distinctions behind the drill. The diagnostic is our teaching framework, not an employer’s scoring system. Inspect the existing guide’s sample to judge the explanation style before paying.

Choose support only for the gap you found

Useful for: Candidates who need structured technical practice after identifying a specific conceptual gap.

Limit: The PDF is self-study material, not individualized grading or a guarantee of interview performance.

89-page technical guide with 306 numbered questions, worked explanations and six linked diagnostic drills.

Current price: $79. Review the contents and sample before purchase. This is the existing edition described on the product page, not a new 2028 edition.

What Investment Banking Interviews Test

Investment banking interviews are designed to assess three core areas: your technical knowledge, your fit with the team, and your genuine interest in the role. Understanding what interviewers are looking for is the first step to effective preparation.

Technical questions typically make up 50-70% of your interviews at the analyst level. These questions test your understanding of accounting, valuation, M&A, and LBO concepts. The remaining time focuses on behavioral questions and your "story", why banking, why this firm, and why you.

Technical Knowledge

Accounting, valuation, M&A mechanics, LBO modeling

Behavioral Fit

Your story, motivations, teamwork examples

Industry Knowledge

Market awareness, deal experience, firm knowledge

Communication

Clear, structured responses under pressure
