Technical and behavioral interview mechanics

#What the technical round is actually testing

IB first-round interviews are overwhelmingly technical-accounting and valuation-mechanics questions, not case-style problem-solving the way consulting interviews run. [Directional] The reason is structural, not arbitrary: an analyst's actual first-year job is building and maintaining financial models and pitch materials, so the interview tests the exact mechanical literacy that job requires on day one — whether a candidate genuinely understands how a company's financial statements connect, not whether they've memorized a script. [Directional]

#The core question set

Three families of technical question recur across bank interview guides, university career-center prep materials, and third-party finance-training content (Training the Street, Wall Street Prep, and similar vendors, several of which are contracted directly by banks and universities to run onboarding and recruiting-prep training — a genuinely closer-to-primary source than a blog summarizing them secondhand): [Directional] for the specific vendor-bank contracting relationships, which weren't independently confirmed for every named vendor in this research pass; [Established] for the question families themselves, which follow directly from standard accrual accounting identities rather than resting on any one source's authority.

• The three-statement linkage. "Walk me through how a $10 increase in depreciation flows through the income statement, cash-flow statement, and balance sheet." Depreciation is a non-cash expense, so it reduces pre-tax income (and, net of the tax shield, net income) on the income statement, gets added back on the cash-flow statement (since it never left as cash), and reduces the property/plant/equipment line on the balance sheet while cash rises by the tax shield — the balance sheet still balances because the reduction in retained earnings from lower net income exactly offsets the net asset change. This is pure double-entry accounting identity, not a matter of firm-specific convention. [Established]
• Valuation methodology. The three standard approaches — comparable company analysis ("comps," valuing a company against the trading multiples of similar public companies), precedent transaction analysis (valuing it against multiples paid in similar past M&A deals), and a discounted cash-flow model (valuing it on its own projected future cash flows, discounted to present value) — and why each can produce a different answer for the same company: comps and precedents reflect what the market or acquirers are actually paying right now, where a DCF is only as good as its own growth, margin, and discount-rate assumptions. [Established] — this is standard corporate-finance methodology, not a contested claim.
• Mental math and quick ratios. EV/EBITDA, P/E, and similar multiples calculated quickly and correctly under time pressure, since a live pitch or live deal conversation doesn't pause for a calculator. [Directional]

#Behavioral: what "why banking" is actually screening for

The behavioral half of an IB interview centers on a small, recurring set of questions — "walk me through your resume," "why investment banking," "why this bank specifically," and a request for a story demonstrating resilience under pressure or attention to detail. [Directional] Interviewers across multiple firms consistently report screening less for a specific "correct" answer and more for whether the candidate's story is genuine, specific to that bank rather than copy-pasted across every bank they're interviewing with, and free of the generic "I love the fast pace and working with smart people" answer that every interviewer has heard hundreds of times. [Directional] — synthesized from recruiter-facing and alumni-interviewer guidance across multiple independent sources, not one firm's own published rubric.

The underlying reason banks weight this so heavily: analyst attrition inside the first two years is expensive to a bank in training cost and deal continuity, so an interviewer is genuinely trying to filter for a candidate who understands what the job actually is (long hours, deadline-driven, detail-obsessed support work) and wants it anyway — not for a candidate who picked banking because it's the most prestigious-sounding option on a career fair table and will quit or perform poorly once the reality sets in. [Directional] Module 04 covers that reality directly, sourced rather than romanticized, precisely so a candidate answering "why banking" actually knows what they're signing up for.

#The generic-answer failure mode

The most commonly cited specific failure pattern across interviewer-facing guidance is a candidate who has clearly prepared the technical material but gives a behavioral answer indistinguishable from every other candidate's — no specific deal, no specific person they spoke with at that bank, no detail that couldn't be copy-pasted into an interview at a competitor. [Directional] The practical fix this pattern implies, independent of any specific script: the coffee chats and networking conversations that get you the interview in the first place are also where the specific, bank-particular material for the behavioral round actually comes from — which is one more reason the non-target pattern in Module 02 isn't optional extra credit even for a target-school candidate.
