Investment Banker · The dealmaker who prices companies and moves capital — a trade running from Medici Florence to today's pitch decks, paid for trust when billions change hands.
From outside, the visible skill is financial modeling — the Excel architecture that turns a company into a valuation. Inside the trade, modeling is considered the easy part, learnable in months. The scarce skills are the surrounding ones: flawless execution under absurd deadlines, judgment about what a number actually implies, and — at the senior end — the ability to make a CEO trust you with the largest decision of their career.
The apprenticeship is deliberately front-loaded with grind. Junior bankers describe the analyst years as a tolerance test wrapped around an education: the hundredth comp table teaches little, but the habit of delivering exact work at 2 a.m., repeatedly, under a managing director's name, is precisely what the industry is screening for. What separates those who rise is the transition from producing the work to originating it.
Sustained 70–95-hour weeks on live deals, with quality expected to be identical at hour one and hour eighty — the trait the analyst years exist to test.
The senior product: boards and founders hire the banker they trust, built over years of being useful before any mandate exists.
A misplaced decimal in a fairness opinion or a wrong share count in a merger model is a fireable, sometimes litigable, error — checking culture is the trade's core discipline.
DCFs, comparable companies, precedent transactions, LBO models — the technical language every argument about price is conducted in.
Running an auction, timing a concession, reading the other side's constraints — the craft that determines the last ten percent of any deal's price.
Turning a valuation into a narrative a board, an investor roadshow or a reluctant seller will act on; the pitch book is rhetoric wearing a spreadsheet.
Emails triaged, the staffing sheet consulted, overnight comments from seniors on yesterday's drafts absorbed. Live-deal checklists reviewed before the day's calls begin.
Update calls with clients, lawyers and counterparties across time zones; the junior banker takes notes that become tonight's revised documents, action items and diligence lists.
The production core of the day: building and updating models, comps and pitch pages, coordinating data-room requests, drafting the materials the seniors will mark up tonight.
Managing directors, freed from their own meetings, return marked-up drafts in the evening — the industry's notorious rhythm that guarantees the junior team's night is only beginning.
Comments processed, numbers re-tied, pages rebuilt; dinner at the desk on the firm's meal stipend. The revised book goes back out for the seniors' morning review.
Home by taxi on the firm's account, a short night, and back. Protected Saturdays — most banks' one formal concession since 2013 — interrupt the cycle roughly weekly.
Craft knowledge practitioners actually pass on — not motivation.
The trade's standard exhibit is the "football field": a single chart stacking valuation ranges from discounted cash flow, comparable companies, precedent transactions and LBO analysis. The point is epistemological — every method is wrong differently, so a defensible price is argued from the overlap of several, never from the false precision of one.
A sell-side banker's leverage is the other bidder — actual or plausible. Auction design is the craft: how many parties to approach, how to sequence rounds and deadlines so each bidder prices the risk of losing, and how to keep tension alive when there is really only one serious buyer at the table.
Every figure in a book must trace to a source and agree with every other appearance of itself — "tick and tie." Analysts print and check pages line by line before anything reaches a client, because a single inconsistent number invites the client to distrust all the rest. The discipline, not the modeling, is what first-year training actually installs.
Siegmund Warburg ran his firm on the conviction that finance is a literary profession: client letters were drafted and redrafted like essays, meetings were minuted the same day in precise prose, and he screened hires partly by graphology. The underlying technique survives him — in a trust business, the quality of your written thinking is the product the client can actually inspect.
Felix Rohatyn's version of relationship banking: advise continuously — board dinners, quiet counsel, unpaid memos — so that when the transaction of a CEO's lifetime arrives, there is no bake-off, only a phone call. The technique is patience with a balance sheet: invest years of unbilled judgment in people before they control a mandate.
Live deals run under project code names — Project Everest, Project Blue — with information restricted to named insider lists, because a leak moves markets and ends careers under insider-trading law. The craft is practical: never name the client in an elevator, keep separate "clean teams" for sensitive competitor data, assume every printer tray is public.
The modeling canvas. Banking's Excel culture is keyboard-only — training programs literally unplug mice — and a bank's model conventions (color-coded inputs, no hardcoded numbers in formulas) function as a shared grammar across every deal team.
Where more junior-banker hours go than any other tool: pitch books, management presentations, board materials. Banks maintain dedicated overnight presentation-production departments, but the analyst owns every number on every page.
The market-data standard at roughly $30,000 a year per seat: live pricing, bond data, league tables and the messaging system over which a remarkable share of the world's deal gossip travels.
The screening and comps engines — financials, multiples, ownership and transaction databases that feed valuation work. Most analysts' first assignment is a comp set pulled from one of them and re-checked against filings by hand.
The sealed digital room where due diligence happens: watermarked documents, permissioned access and complete audit logs of who read what. Sell-side juniors run it; the access log itself is deal intelligence about which bidders are serious.
The hours are survivable as a two-year sprint and corrosive as a decade; burnout, health collapse and abrupt exits cluster in years three to five. The 2021 Goldman Sachs first-year survey — 95-hour weeks, five hours of sleep — merely published what the industry privately priced in, and the analysts who thrive treat energy as a managed resource, not a virtue.
Execution skill carries a banker to vice president and no further; the MD gate is revenue, which requires relationships, sector conviction and commercial nerve that pure production years never build. The industry's saddest common figure is the superb VP passed over repeatedly because nobody taught them, in time, that the job changes species at the top.
Bankers live permanently inside material non-public information, and the line is criminal, not ethical. The 1986 Dennis Levine and Ivan Boesky cases — which ultimately helped destroy Drexel Burnham Lambert — remain the trade's cautionary scripture: tips to a friend, a personal account, a leaked mandate, and a career, a firm and often liberty end together.
The person who starts the company — spotting the gap, bearing the risk and answering for payroll, from Assyrian caravan financiers to venture-backed founders.
