Getting started

IB or consulting: pick the product, then the interview

Decide between investment banking and consulting with HBS pay data, firm interview formats, and curated prep paths for both tracks without mixing them.

UpdatedReviewed by Ned

Most candidates treat investment banking versus consulting as a lifestyle fork. The interview rooms treat it as a product fork: banks hire people who close transactions under a model; firms hire people who own a recommendation under ambiguity. Prep one track as if it were the other and you fail the filter that actually scores you.

After this hub you should be able to choose a path with public numbers, map both interview funnels without mixing formats, and open the right CoachNed guides in order.

The decision table: pay, hours, exits, skills

Banks and consulting firms almost never publish first-year all-in pay on careers pages. The cleanest public comparison at MBA level is Harvard Business School's Class of 2025 employment data. Consulting took 21% of the class at a $190,000 median base, with median signing $30,000 (91% receiving) and median variable $40,000 (about 90% receiving). Investment banking took 6% at a $175,000 median base, with median signing $50,000 (90% receiving) and median variable $82,500 (76% receiving).

Do the year-one cash math yourself: consulting ≈ $190k + $30k + $40k = $260k; IB ≈ $175k + $50k + $82.5k = $307.5k. At HBS medians, banking wins cash by roughly $47k, while consulting wins base certainty and a higher share of the class. Undergrad analyst bands move every cycle and are mostly self-reported; treat forum screenshots as folklore until you have an offer letter. Hours folklore is even noisier: neither side publishes a weekly hour guarantee, so use coffee chats and offer letters, not Reddit averages, when you price lifestyle.

Decision lensWhat to readWhat the evidence favors
Product and scoreboardConsulting vs investment banking, consulting vs financeBanking sells closed deals; consulting sells staffed recommendations
Cash shapeConsulting salary guide, 2026 salary report, McKinsey salary, BCG salary, Bain salaryIB bonus dominates year-one; consulting base is flatter and more certain
Hours and lifestyleDay in the life, is consulting right for youBoth are hard; banking compresses more weeks into deal spikes
ExitsConsulting exit opportunities, PE vs MBB, consulting career pathBanking feeds buy-side finance; consulting feeds broader industry and PE diligence seats
Fit testWhy consulting, STAR for consultingIf your "why" is lifestyle or prestige only, both rooms fail you

Read the product column before the cash column. The HBS gap is real and useful; it is not a reason to sit a case interview you will hate on a client study, or a paper LBO you will hate at 1 a.m. on a live deal.

Ned's rule. Choose the product you want to ship on a bad Tuesday, not the logo you want on LinkedIn. The interview is just a filter for that product.

Worked example: one profile, one favored path

Candidate A is a junior finance major. She can walk a three-statement model without notes, already prefers closed-ended correctness over open-ended scoping, and wants a PE associate seat within four years. Candidate B is a history major who likes ambiguous problems, gets energy from client storytelling, and wants optionality across industries rather than a buy-side ladder.

Run the table above against each. For A, the HBS cash gap is a bonus, not the thesis: her skills map to technicals, HireVue market commentary, and a PE exit story. Banking is the favored path; consulting is a hedge only if she can sit a real case without turning it into a valuation recital. For B, the same HBS numbers are not decisive: her comparative advantage is the case and PEI-style stories. Consulting is favored; banking is a hedge only if she is willing to rebuild accounting and valuation from scratch.

Score yourself the same way. Write three bullets: what you want to produce in year two, which interview format you can honestly practice five hours a week, and which exit you would take if both offers arrived tomorrow. If those three bullets disagree, fix the decision before you fix the flashcards.

If you are sitting both, keep two calendars. Do not "save time" by treating a DCF walkthrough as case prep.

The IB interview track

JPMorganChase's hiring page is unusually honest: the interview process "will differ for each position," and strong candidates meet several people across multiple rounds. Banks do not publish a universal HireVue script. Your invitation controls timing, retries, and whether an on-demand video sits before live rounds. Goldman's New Analyst Program describes the job as learning the firm's businesses and building skills to support them; it does not publish pay or interview question banks.

That silence matters. Prep sites invent "standard" question counts; the primary sources do not. Train the skills the bank can observe on camera and in a live room: crisp motivation, a current market view you can defend, accounting links without a blank stare, and a valuation walk that names when a method lies.

StageWhat interviewers scorePrep on CoachNed
Screen / HireVueMotivation, market awareness, concise delivery under a clockIB HireVue questions, HireVue format
Accounting technicalsThree statements, links, working-capital trapsIB accounting questions

LBO / merger techSources and uses, IRR intuition, accretionLBO interview questions, LBO model, merger model questions
Behavioral / SuperdayOwnership, intensity, why this bankIB behavioral questions, Lazard, Houlihan Lokey

The Superday is not a consulting final. Expect stacked technicals and bank-specific stories, not a 25-minute profitability case. If an interviewer asks "walk me through a DCF," answer the method; do not open with a MECE tree.

The consulting interview track

McKinsey's interviewing page states the standard shape for most client-facing roles: a personal experience interview, then a problem-solving (case) interview; some roles add expertise interviews or online assessments. That is the opposite scoring sheet from a bank technical. You are graded on how you structure ambiguity, do audible math, and close with a recommendation the interviewer can act on.

BCG, Bain, and the Big Four change labels and online tests by office and year, but the core split stays: a story that survives probes, plus a case that earns points for structure and synthesis. Firm-specific guides matter once you have an invite; the table below is the shared spine.

StageWhat interviewers scorePrep on CoachNed

Fit / PEI / behavioralSpecific stories that survive follow-upsConsulting behavioral, McKinsey PEI, Bain fit, BCG behavioral
Process mapRounds, thank-yous, reapplicationInterview process, how to get into consulting, prep timeline

If you only have banking technicals, start with a scored structure drill, not another merger model. The first leak I see from dual-track candidates is silent math: they can compute EV correctly on paper and still lose the case because they never said the equation out loud.

Practice

Structure drill

Write an opening tree on a fresh prompt and get scored on MECE branches, not a memorized framework.

Start a drill

What transfers (and what does not)

Dual-track recruiting only works if you are honest about transfer. Arithmetic and composure travel. Deal jargon and "I built a model" stories usually do not, unless you rewrite them into client impact and a recommendation.

SkillTransfers?Where it shows up
Mental arithmeticYesCases and paper LBOs; drill case math and mental math
Three-statement fluencyPartialHelps banking cases and financial services cases; does not replace issue trees
Valuation instinctsPartialUseful in M&A cases and PE diligence; over-modeling loses case points
STAR storiesYes, if rewrittenBanking behavioral ≠ McKinsey PEI; rewrite for tell me about yourself
Deal process triviaNoRarely scored in consulting; can poison a why consulting answer
Ambiguous scopingConsulting-only muscleTrain on finance cases that still demand a recommendation, not a WACC

The crossover trap: candidates recite Enterprise Value formulas in a profit case, or invent a fake "case" in a bank technical when the banker asked for the three statements. Different rooms, different sheets. If you want one shared weekly habit, make it timed verbal math; everything else stays on separate tracks.

Practice this week if you are on both tracks

  1. Write a one-page decision memo using the HBS cash math above and your own exit preference. Pick a primary path.
  2. Sit one banking HireVue prompt out loud under two minutes: why this bank, one market view, one ownership story. Use the IB HireVue guide.
  3. Sit one consulting case the same day. Start with /start (three typed turns, instant scores, no account) or the live voice room at /interview. Everything is open for seven days, no card; then $120 for a recruiting season or $49 a month.
  4. Rewrite one behavioral story twice: once for a bank Superday, once for consulting PEI. If the second version still sounds like "I closed the model," it will fail.

Frequently asked questions

Can I recruit for investment banking and consulting at the same time?

Yes, if you keep two prep banks and two calendars. The failure mode is treating technicals as case practice. Use the decision table first so your coffee-chat and "why" answers do not contradict each other across industries.

Does investment banking pay more than consulting in year one?

At HBS Class of 2025 medians, investment banking's base-plus-signing-plus-variable package lands higher than consulting's, driven by the variable bonus. Bases alone favor consulting. Undergrad and non-MBA markets differ; trust offer letters over screenshots.

What is the biggest interview difference between banking and consulting?

Banks lean on technical correctness and deal process; consulting lean on structuring ambiguity and a client recommendation. McKinsey publishes the personal-experience-plus-case pattern; JPMorganChase publishes that processes differ by role and span multiple rounds.

If I already know accounting, am I ready for cases?

No. Accounting helps you read a P&L exhibit. Cases still score how you set the tree, run audible math, and synthesize. Start with structure and a full case, not more valuation drills.
