Investment banking has a peculiar reputation: a profession simultaneously envied for its compensation and pitied for its demands. The stories of 100-hour work weeks, analyst slide decks completed at 3am, and relentless client pressure are not entirely myth. But neither is the compensation, the professional network, or the accelerated exposure to high-stakes financial transactions that analysts receive in their first two years. Understanding what investment bankers actually do — and what they trade to do it — is essential for anyone considering the path.
The term 'investment banking' covers several distinct activities that are often conflated. An investment banker could be an M&A adviser helping two companies structure a merger. They could be an ECM banker managing a company's IPO. They could be a DCM banker arranging a debt issuance. In all cases, the bank acts as an intermediary and adviser, earning fees for facilitating transactions rather than risking its own capital (in the traditional advisory sense — trading desks are a separate business).
This article explains the full mechanics of the investment banking career: what analysts and associates actually do day-to-day, how deals work, what the salary progression looks like, what culture is really like, what exit opportunities arise, and how to evaluate whether the trade-off is worth making for your particular circumstances and goals.
"Investment banking is a place where smart, ambitious people are willing to be treated terribly for a few years in exchange for a credential that opens almost every door in finance." — Anonymous former Goldman Sachs analyst, widely quoted in industry forums
Key Definitions
Bulge Bracket: The largest global investment banks — Goldman Sachs, Morgan Stanley, JP Morgan, Bank of America, Citigroup, Barclays, Deutsche Bank, Credit Suisse (now absorbed), UBS. Characterised by full-service capabilities and global reach.
Elite Boutique: Independent advisory firms (Lazard, Evercore, Centerview, PJT Partners, Moelis) that focus on advisory services without the capital markets and lending business of bulge brackets. Often pay as well or better than bulge brackets for advisory talent.
Leveraged Buyout (LBO): A private equity acquisition strategy financed largely with debt secured against the target company's assets and cash flows. Investment bankers advise on LBOs and model them extensively; PE firms execute them.
Pitch Book: A presentation prepared by investment bankers to market their services to potential clients or present deal options. Pitch book production is a major time consumer for junior bankers.
League Tables: Rankings of banks by deal volume or value in specific transaction categories (M&A, ECM, DCM). Cited heavily in pitch books as evidence of capabilities.
What Investment Bankers Do Day-to-Day
The daily work is heavily dependent on seniority. Investment banking has a clear hierarchy: Analyst (years 1-2), Associate (years 3-5 post-MBA or promoted analysts), Vice President (years 6-8), Director/Executive Director (years 8-11), and Managing Director (MD). The division of labour is stark.
Analysts are the production engine. Their primary activities include:
- Building and maintaining financial models (DCF, LBO, merger models, accretion/dilution)
- Preparing pitch books and client presentations
- Conducting industry and company research
- Running due diligence processes (coordinating information requests, reviewing data rooms)
- Managing the logistics of live transactions (tracking signing conditions, coordinating with lawyers, accountants, and counterparties)
Associates oversee analyst work, interface with clients on day-to-day matters, and take on more direct project management responsibilities.
VPs and Directors manage client relationships day-to-day, coordinate transaction execution, and begin significant business development activity.
Managing Directors are primarily revenue generators — originating mandates, maintaining senior client relationships, and winning competitive bids. A good MD brings in more revenue than their entire team costs.
Deal Types
Mergers and Acquisitions (M&A): The advisory business most associated with investment banking in the public imagination. Banks advise either the acquirer (buy-side M&A) or the target (sell-side M&A, or 'defence' work) in corporate transactions. Fees are typically 0.5-1.5% of transaction value for mid-market deals, declining to 0.1-0.5% for very large transactions. A $500 million deal at 1% generates $5 million in fees.
Equity Capital Markets (ECM): Helping companies raise equity capital. The flagship transaction is an IPO (Initial Public Offering), where a private company lists shares on a public exchange. Banks also manage follow-on offerings (additional shares from already-listed companies), rights issues, and convertible bond issuances. ECM fees on IPOs typically run 3.5-7% of total proceeds.
Debt Capital Markets (DCM): Arranging bond issuances and structured debt products for corporations and governments. Investment-grade bond issuance fees are typically 0.2-0.4% of proceeds; high-yield bond fees run higher. DCM is a higher-volume, lower-margin business than M&A or ECM.
Leveraged Finance: A sub-division that arranges debt specifically for private equity-backed leveraged buyouts. Closely connected to the private equity industry and a common feeder into PE careers.
Restructuring: Advising companies and their creditors during financial distress, debt restructuring, or bankruptcy. Counter-cyclical — activity increases when other deal types slow down. A specialised area that requires deep understanding of credit, bankruptcy law, and negotiation dynamics.
Culture and the Analyst Experience
The analyst experience has been extensively documented, debated, and modestly reformed in recent years. The reality in 2024 is that hours remain extremely long by any normal standard, though the worst excesses of the pre-2008 era have been somewhat moderated by competitive talent markets.
What is still true:
- 80-100 hour weeks during active deal periods are normal at bulge brackets
- 'Face time' culture persists at many banks — being seen in the office matters
- Last-minute revisions and overnight turnarounds are routine on live deals
- The work is primarily execution rather than strategy at junior levels — building models and creating slides to a precise specification
What has improved:
- Protected Saturdays (no work assigned until Sunday) exist at some banks following junior banker wellbeing initiatives
- Base salaries increased dramatically in 2021 following widespread burnout reports and analyst attrition
- Remote work flexibility has been partially maintained post-COVID at some groups
The cultural experience varies enormously by group, bank, and geography. Restructuring groups and some industry coverage groups have reputations for better or worse cultures that are worth researching through network conversations before accepting an offer.
Salary and Compensation
US Bulge Bracket (2024 estimates):
Analyst Year 1: $110,000 base + $80,000-$120,000 bonus = $190,000-$230,000 all-in Analyst Year 2: $110,000 base + $90,000-$150,000 bonus = $200,000-$260,000 all-in Associate Year 1 (post-MBA): $175,000-$200,000 base + $100,000-$175,000 bonus = $275,000-$375,000 VP: $250,000-$350,000 base + $200,000-$400,000 bonus = $450,000-$750,000 Director/ED: $350,000-$450,000 base + $400,000-$700,000 bonus = $750,000-$1,150,000 Managing Director: $500,000-$800,000 base + $1,000,000-$5,000,000+ bonus (highly variable)
UK figures are lower — London analyst all-in compensation typically runs £90,000-£130,000 in year 1.
Elite boutiques (Centerview, Evercore) often pay more than bulge brackets at analyst and associate levels due to simpler cost structures and higher per-banker revenue.
Exit Opportunities
Investment banking analyst programmes are, for many participants, a deliberate two-year training ground before moving into a more desirable role. The most common exits:
Private Equity (most sought after): Two-year IBD analysts are the primary recruiting target for leveraged buyout PE firms. The analytical skills (financial modelling, due diligence) transfer directly. Recruits from Goldman, Morgan Stanley, and Evercore go to flagship PE funds (KKR, Blackstone, Apollo). Compensation can be higher than banking.
Venture Capital: Less common directly from banking than PE. VC firms value operational and market insight over financial modelling skill, so bankers who have worked in technology or healthcare coverage groups are better positioned. Many VC associates first do PE before transitioning.
Hedge Funds: Event-driven and credit-focused hedge funds recruit directly from banking. Fundamental equity hedge funds sometimes hire directly from IBD analysts with strong sector research experience.
Corporate Development: M&A roles within operating companies — managing acquisitions, divestitures, and strategic investments from the corporate side. Lower compensation than banking but better hours, and the work is often more strategically interesting.
MBA: The most common exit for those wanting to reset into consulting, tech, or broader finance roles. A Wharton, Harvard, or LBS MBA is highly accessible following 2 years of IBD experience and opens a wide range of post-MBA career paths.
Is It Worth It?
The honest answer is: it depends entirely on what you are optimising for and what alternatives you have.
The case for it: The compensation is extraordinary by almost any comparison. The professional network is valuable for decades. The two-year analyst experience compresses significant financial learning. The exit opportunities are unmatched in terms of breadth and quality.
The case against it: The opportunity cost of two years at 90+ hours per week is not just personal time — it is the foregone early career development in a field you might prefer. Many people who go into investment banking because it is 'prestigious' or 'pays well' find the work genuinely unrewarding. The work at analyst level is largely mechanical execution rather than strategic thinking. Burnout rates are high.
The people who thrive long-term in investment banking are generally those who genuinely find the work interesting — the mechanics of deal structuring, the competitive dynamics of pitching for mandates, the client relationship dimension. Those who are primarily motivated by compensation and prestige tend to exit earlier and often find comparable compensation in less punishing environments.
How to Break In
The standard path: Target university degree (economics, finance, mathematics, or engineering), competitive summer internship in investment banking after your penultimate year, convert to a full-time offer. The vast majority of full-time analyst offers go to returning interns. Applications typically open a year in advance.
The MBA path: For career changers or those from non-target universities, an MBA from a top school provides a structured route. Most banks hire associates primarily through MBA programmes.
Non-target university path: Possible but harder. Requires exceptional grades, relentless networking, and often starting in a regional office, smaller boutique, or back-office role before lateral movement.
Technical skills: Excel proficiency is essential. Basic understanding of accounting (income statement, balance sheet, cash flow) is expected on day one. Familiarity with M&A concepts (synergies, enterprise value, EBITDA multiples) signals seriousness.
Practical Takeaways
Start networking with investment bankers through LinkedIn and alumni connections a full year before you intend to apply. Do not wait for applications to open. Prepare a 'stock pitch' and understand current M&A markets — interviewers consistently ask what deals you have been following and why. If a bulge bracket is not accessible from your university, start at a regional boutique and move laterally once you have a year of deal experience.

How many hours do investment bankers work?
First and second-year analysts at bulge-bracket banks typically work 80-100 hours per week during active deal periods. 'Lifestyle' boutiques and some coverage groups average closer to 60-70 hours. The hours improve significantly at VP level and above, though deal flow still drives spikes.
What is the starting salary for an investment banking analyst?
After pay raises driven by the 2021 talent war, first-year analysts at bulge-bracket US banks earn \(110,000 base salary plus an \)80,000-\(120,000 year-end bonus, totalling \)190,000-$230,000 all-in. Elite boutiques and top regional firms pay comparably.
What are the main exit opportunities from investment banking?
The most common exits are private equity, venture capital, hedge funds, corporate development (M&A roles at operating companies), and corporate finance. Two years of IBD analyst experience is specifically valued by PE firms conducting leveraged buyouts.
Do you need an MBA to advance in investment banking?
An MBA from a top school (Wharton, Harvard, Columbia, LBS, INSEAD) is the standard route from analyst to associate for career changers. Those promoted directly from analyst to associate within a bank can avoid the MBA, but most banks have limited associate promotion spots.
What is the difference between M&A and ECM in investment banking?
M&A (Mergers and Acquisitions) advises companies on buying, selling, or merging with other businesses. ECM (Equity Capital Markets) helps companies raise money by issuing shares, including in initial public offerings (IPOs). DCM (Debt Capital Markets) handles bond issuances and loan arrangements.
