Industry Fundamentals
What the job actually is, before any of the recruiting apparatus around it. Four divisions, two kinds of transaction, and the org logic that decides which deals land on your desk.
Four divisions, two transaction types
Investment banks contain four main divisions: asset management, equity research, sales & trading, and investment banking itself. "Investment banking" as a job title refers specifically to the last of these — the advisory business.
Banks earn an advisory fee (a small percentage of transaction volume — on a $1bn deal, sub-1%, but that's still tens of millions) on two kinds of transaction:
Capital raises
- Equity deals: IPOs, follow-on offerings (a public company issuing more shares), convertible bonds
- Debt deals: bank debt, high-yield bonds, investment-grade bonds
M&A
- Sell-side: banks always prefer this — you're paid when the deal announces and closes
- Buy-side: paid only if your client wins; often just a retainer if they don't, since one of several bidders always loses
Product groups vs. coverage groups
Banks organise their bankers one of two ways — sometimes both at once.
Product groups
- One transaction type (e.g. M&A, ECM, DCM) across many industries
- Deep expertise in a transaction, broad industry exposure
- Drawback: pigeonholed exit options, especially in ECM/DCM. M&A product groups are the exception — exits are wide open
Coverage groups
- One industry (e.g. healthcare, TMT), all transaction types
- Deep view of an industry's landscape, exposure to varied deal types
- Drawback: you won't enjoy every transaction type equally — heavier on presentation and pitch work when a deal doesn't materialise
Goldman Sachs runs almost entirely on coverage groups; JPMorgan keeps a separate M&A product group; elite boutiques like Evercore and Centerview are M&A-only by design. The split is bank-specific — check each one individually.
Five ways banks add value
- Maximise financial outcomes — the right price for equity, the right amount of debt, the highest price on a sale.
- Process management — running due diligence, data rooms, and legal coordination that a company can't run on its own expertise.
- Understanding market climate — knowing when to launch and when to shelve. An IPO can die in the week markets tank after months of prep.
- Connecting companies — senior bankers hold the relationships (Michael Grimes at Morgan Stanley knowing Zuckerberg, Cook) that a $500m company can't get on its own.
- Industry & product knowledge — pattern-matching a tricky situation against every similar deal the bank has seen before.
Bank tiers, and the ladder inside one
| Tier | Focus | Typical deal size | Examples |
|---|---|---|---|
| Bulge bracket | All products, all industries, global | up to $50–100bn | Goldman Sachs, Morgan Stanley, JPMorgan, BofA |
| Elite boutique | Mostly M&A, non-capital-intensive | $1bn – 20bn+ | Evercore, Centerview, Lazard |
| Middle market | All products, smaller-revenue clients | $0.5bn – a few bn | Jefferies, Piper Sandler, Raymond James |
| Boutique | One industry or function, small deals | sub-$500m | varies widely |
- Managing Director — reviews pitch books, brings the client relationships that generate the deals; the rainmaker role, worth 80%+ of the value chain.
- Director / SVP / Principal — starts forming client relationships directly; barely touches models or decks anymore.
- Vice President — present at client meetings, gives direction to analysts and associates, but not yet owning the relationship.
- Associate — double-checks the analyst's work cell by cell, builds some pages and models directly.
- Analyst — the workhorse; builds the model from scratch, 60–90% of the underlying work.
Accounting
The three statements, how they connect, and the handful of rules that make each one behave the way it does. This is the part your Google Doc already covers in full — kept here as a complete, illustrated reference rather than something to re-read line by line.
The income statement
Reports a company's revenue, costs, expenses and profit or loss over a period of time.
The line-by-line walk a banker expects in an interview — memorise the sequence, not just the words:
Three rules for what belongs on it
- Must fall 100% within the period. Rent spanning 2025–2027 on a 2025 income statement only shows the 2025 slice.
- Must affect the company's taxes (and so net income). Debt repayment and dividends flow straight to the balance sheet — they never touch the income statement.
- Must be a revenue, expense, gain, or loss. Gains/losses are non-core: asset sales, lawsuit settlements, FX moves. Never debt repayment, dividends, or CapEx — none of those are gains or losses.
Accrual accounting
Measures performance based on when things happen, not when cash moves — the single most-tested concept in banking accounting interviews.
Two rules do all the work:
The cash flow statement
Revenue isn't cash. EBIT isn't cash. EBITDA isn't cash. Net income isn't cash. Only cash is cash — and cash generation is the true measure of a company's value (ask BlackBerry).
If you could only keep one statement, it's this one — it reconciles non-cash accounting items (AR, inventory) back to real cash, and captures flows the income statement never sees at all (CapEx, debt raised).
What counts as a non-cash add-back?
Any expense that reduced net income without any actual cash leaving the business gets reversed here. The two you'll see in almost every example in this document are D&A (spreading an asset's cost over its life) and stock-based compensation (paying employees in shares rather than cash) — both covered in full back in the income statement section above.
Real-world cash flow statements usually carry a few more. Impairment / write-downs — marking an asset's recorded value down on paper (say, goodwill from an acquisition that isn't performing), with no cash changing hands. Deferred taxes — the gap between the tax expense shown for accounting purposes and the actual cash tax paid this year, caused by timing differences between tax rules and accounting rules. Unrealized gains or losses — a paper gain on an investment still being held, or an FX translation swing — the same kind of item that sits in AOCI on the balance sheet.
The test is always the one from the income statement rules: did this actually cost, or bring in, real cash this period? If not, it gets added back (or subtracted, for a non-cash gain) here.
The balance sheet
Assets = Liabilities + Shareholders' Equity
Assets are what a company owns that generates future cash. Liabilities are what it owes. Shareholders' equity is what the owners keep once everything else is paid — it is both a source of funding and a running scorecard of value created.
| Current (≤ 1 yr) | Non-current (> 1 yr) | |
|---|---|---|
| Cash & equivalents, marketable securities, accounts receivable, inventory, prepaid expenses | Assets | Long-term investments, PP&E, intangibles, goodwill, deferred tax assets, equity-method investments |
| Revolver, current portion of LTD, accounts payable, accrued expenses, deferred revenue | Liabilities | Long-term debt, lease liabilities, deferred tax liabilities, pension liabilities |
Shareholders' equity, line by line
Expand each line item for what the abbreviation stands for, the plain-language definition, and a quick worked number.
Common Stock at par value
The legal "stated" value of every share issued and outstanding. Par value is a deliberately tiny, arbitrary number — often $0.0001 or $0.01 a share — and it never moves, no matter what the stock actually trades for.
100 shares × $0.01 par = $1 common stock, regardless of what those shares were actually sold for.
APIC Additional Paid-In Capital
Also called surplus capital. The cash shareholders paid above par value when the shares were first issued — effectively "total cash raised, minus the par value sliver." Like common stock, it's frozen at the moment of issuance and doesn't move with the share price afterward.
100 shares sold at $10 each = $1,000 raised. Common stock = $1 (above). APIC = $1,000 − $1 = $999.
Preferred Stock
A separate class of ownership carrying a fixed dividend and priority over common shareholders if the company is liquidated. It gets its own par value and APIC lines when a company has it — most don't. The video's own estimate: roughly 1–5% of companies carry preferred stock at all.
Retained Earnings RE
The single most-tested line item in this whole section, and the direct thread connecting the income statement to the balance sheet: prior retained earnings + net income − dividends. A brand-new company starts at $0.
Year 1: $0 + $100 net income − $0 dividends = $100. Year 2: $100 + $200 net income = $300.
AOCI Accumulated Other Comprehensive Income
A catch-all for gains and losses the company hasn't actually "realized" through a sale yet — unrealized gains or losses on investments still being held, and currency-translation adjustments from converting an overseas subsidiary's books back into the parent's reporting currency.
Say a company holds $500k of bonds it bought at par, and rates move so they're now worth $520k on paper. It hasn't sold them — no cash has changed hands — so that +$20k can't go through net income. It sits in AOCI instead. Same logic if a UK subsidiary's £10m of assets are suddenly worth $12.6m instead of $12.4m purely because GBP/USD moved: the $200k swing lands in AOCI, not the income statement.
Treasury Stock
The cost of shares the company has bought back on the open market but not formally retired. It's a contra-equity account — it always shows up as a negative number, reducing total shareholders' equity.
NCI Non-Controlling Interest
The slice of a majority-owned subsidiary (>50% owned, but not 100%) that belongs to someone else. Own 75% of a company and you still have to consolidate 100% of its financials — the other 25% is isolated here as NCI. It comes back in a bigger way in Part III.
One company, three statements, fully tied together
Synthetic figures — built to teach the connections, not a real filingEverything above is easier to hold onto against one real-looking set of books.

Equity Value & Enterprise Value
Two different answers to "what is this company worth?" — and the foundation every valuation method in Part IV builds on.
The house analogy
Equity value, properly
Value to only equity shareholders after all debt and other obligations are satisfied. In theory: market value of total assets − market value of total liabilities = market value of common shareholders' equity.
Three ways to calculate it — but for public companies, only one matters in an interview:
$213/share × 14.84bn diluted shares = $3.16 trillion — i.e. the market cap.
The video quotes $3.17tn; the inputs as stated multiply to 3.161, so treat the final digit as rounding in the share price or share count, not a different method.
Shareholders' equity (book value) includes preferred stock and NCI; equity value doesn't. Book value is historical cost — what was actually paid, frozen on the day it happened. Equity value is forward-looking market opinion — what investors believe the company can generate in cash from here.
$500m buildings + $200m inventory + $100m patents − $300m debt = $600m book value. The company trades at $1,200m equity value.
Equity value ÷ book value = 2.0× — the market sees roughly double the value the accounting record shows, priced on growth and earning power the balance sheet can't capture.
Investor hierarchy
Different capital comes with different liquidation priority — the order investors are paid if a company sells everything and winds down.
Enterprise value
The value of core business operations to all investors — capital-structure-neutral, and often described as a company's takeover price.
EV $7,000m, preferred $200m, debt $2,000m, NCI $300m, cash $3,000m.
Equity value = 7,000 − 200 − 2,000 − 300 + 3,000 = $7,500m
Non-operating items get stripped out because EV is meant to reflect only core operations: excess cash, marketable securities, minority stakes in unrelated businesses, assets held for sale, excess PP&E not used in operations.
Non-controlling interest
Own >50% of a company and accounting rules force you to consolidate 100% of its financials into your own — even the sliver you don't own. NCI is how enterprise value accounts for that unowned sliver, so that a multiple like EV/EBITDA compares like with like.
Valuation
The most heavily-tested topic in banking interviews, and the actual day-to-day of the job — comps, precedents, and the discounted cash flow.
Relative vs. intrinsic
Relative
- Trading comps — what similar public companies trade at
- Transaction comps — what similar companies sold for
Intrinsic
- Discounted cash flow — what the business itself can generate
- LBO, dividend discount model (the latter mostly for financial institutions)
There's no single correct valuation — only a more or less defensible one. Bankers triangulate across all of these into a football field: a range built from the 52-week trading price, analyst targets, trading comps, transaction comps, and the DCF stacked side by side.
Trading comps
A relative valuation methodology comparing financial metrics across a set of similar public companies to determine a target's valuation.
Build the peer set
4–8 companies, similar on business model, industry, geography, size, and financial profile. More than ~15–20 stops helping — you're no longer comparing like with like.
Select, collect, calculate
Pick metrics that fit the company's stage (revenue multiples for growth, EBITDA/P·E for mature), pull the data, calculate the multiples.
Analyse & value
Choose a defensible multiple range from the peer set, apply it to the target's own metric.
| Peer group | Companies | Why they qualify |
|---|---|---|
| Streaming | Disney, Comcast, Warner Bros. Discovery, Paramount | Direct streaming competitors, despite very different broader businesses (theme parks, cable) |
| Traditional media | AMC Networks, Lionsgate, Fox, Sony | Studios producing the same kind of content |
| Broader tech | Alphabet, Meta, Amazon, Spotify | Netflix is fundamentally a tech company at its core |
| Company | Share price | Mkt cap | EV | Rev growth '26E | EBITDA margin | EV/EBITDA | P/E |
|---|---|---|---|---|---|---|---|
| Disney | $105 | $190bn | $235bn | 3% | 18% | 9.2× | 19.4× |
| Comcast | $38 | $145bn | $260bn | 1% | 27% | 6.8× | 10.2× |
| Warner Bros. Discovery | $10 | $24bn | $55bn | −3% | 15% | 6.1× | — |
| Paramount | $12 | $9bn | $22bn | 0% | 11% | 7.4× | — |
| Netflix (target) | $1,150 | $495bn | $505bn | 9% | 30% | 15.8× | 32.1× |
Target's 2026E EBITDA = $100m. Peers trade at 10×–15× 2026E EBITDA.
Low end: 100 × 10 = $1.0bn · High end: 100 × 15 = $1.0bn – $1.5bn range
Transaction comps
A relative valuation methodology comparing financial metrics across a set of previously completed M&A transactions similar to the one being analysed.
| Trading comps | Transaction comps | |
|---|---|---|
| Time horizon | Present / future (NTM) | Historical, at time of deal (LTM / NTM) |
| Peer criteria | Strict | Looser — smaller universe of deals |
| Includes a premium? | No | Yes — inflates the multiple |
| Needs updating? | Constantly | Never, once built |
| Reliability | Good — same-day market conditions | Weaker — conditions vary deal to deal |
| Typically yields the | Middle valuation | Highest valuation of the three methods |
| Acquirer | Target | Announced | EV | LTM EBITDA | NTM EBITDA | Premium |
|---|---|---|---|---|---|---|
| Argon Capital | Fleetbase | Aug 2022 | $1,850m | 16.0× | 12.5× | 28% |
| Vantage Holdings | Ridgeline SaaS | Nov 2022 | $980m | 14.2× | 11.0× | 24% |
| Union Point Partners | Metric Works | May 2023 | $1,410m | 11.5× | 9.2× | 21% |
| TechSphere | CloudNova | Mar 2024 | $3,600m | 12.0× | 9.5× | 32% |
| Solera Group | Northlight | Jan 2024 | $2,240m | 10.0× | 8.0× | 19% |
Acquisition premium
The % difference between the offer price per share and the target's unaffected share price — the incentive to give up control, remove execution risk, and beat other bidders. Typical range: 10–30%, with 30% a safe answer if asked for one number.
Trades today at 9.5× LTM EBITDA / 8× NTM EBITDA. Five precedent deals in the sector closed at 10×–16× LTM and 8×–12.5× NTM (premium-inflated, so naturally above where ByteTech trades unowned).
LTM: $200m × [10×–16×] = $2.0bn – $3.2bn EV
NTM: $225m × [8×–12.5×] = $1.8bn – $2.8bn EV
The discounted cash flow
A dollar today is worth more than a dollar tomorrow — you could invest it and earn a return in the meantime.
Option A: $100k in one year + $100k in two years. Option B: $180k today. Assume a reliable 10% annual return.
PV(yr 1) = 100,000 / 1.10 = $90,909
PV(yr 2) = 100,000 / 1.10² = $82,645
Total PV of Option A = $173,554 — less than the $180,000 on the table today. Take Option B.
An intrinsic valuation methodology based on a company's future free cash flows. Project cash flow 5–10 years, calculate terminal value (exit multiple or perpetuity growth), discount both back at the WACC to reach enterprise value.
Step 1 — unlevered free cash flow
Available to all investors, debt and equity alike — which is why it starts from EBIT (before interest) rather than net income. Explicit forecast period: 5 years for mature, stable companies; 10 for early-growth; 15–25 for long-ramp industries like biotech, where negative cash flow can run for years before a drug approval flips the switch. The governing rule: forecast as far as the assumptions stay defensible, then hand the rest to terminal value.
Step 2 — WACC
Step 3 — terminal value
Perpetuity growth
TV = FCF
- Grounded in economic theory
- g typically 2–3% — a company can't outgrow the economy forever
- Very sensitive to small changes in g or WACC
Exit multiple
TV = Final-year EBITDA × exit multiple
- Simple — it's just a comps analysis
- Anchored to real market data
- Reintroduces market noise into an otherwise intrinsic model
Year-5 EBITDA $200m × 8× exit multiple = $1.6bn terminal value
Steps 4–5 — discount, then bridge to share price
For a private company there's no market share price to compare against — the DCF simply stops at enterprise value or equity value.
Practice
Drills, sorting exercises and full worked cases, each marked the moment you answer rather than at the end. Nothing is recorded — reset any drill and run it again. Distractors are built from the mistakes people actually make, so expect to have to reason or calculate rather than spot the odd one out. Recruiting fundamentals are deliberately excluded; everything here is technical.
Accounting drills
Sort the line items
The fastest way to stop second-guessing where something belongs. Drag an item into a bucket — or tap the item, then tap the bucket. It turns green or red the instant it lands, and you can move it again until it's right.
