The term “investment banking” often evokes images shaped by films and sensational media coverage—lavish parties, high-stakes deals, and unrelenting hours. While there is some truth behind the industry’s fast-paced nature, the day-to-day reality is more structured and collaborative than most people imagine. Understanding what investment bankers actually do can serve as a crucial first step for those aiming to build a successful career in finance or entrepreneurs seeking to tap capital markets.
This article demystifies investment banking by examining firm rankings, common job responsibilities, typical work hours, hierarchical structures, and compensation. It also highlights the advantages and drawbacks of this field, helping you make an informed decision about whether it aligns with your professional goals.
Investment banking is not a single monolith. Rather, the industry comprises different types of firms categorized by reputation, deal size, and global reach. While prestige matters in many corners of finance, each tier presents distinct learning opportunities and professional challenges.
Bulge Bracket Banks (Tier 1A and Tier 2):
The most prominent global institutions fall into Tier 1A, including Goldman Sachs, Morgan Stanley, and JPMorgan. They typically advise on deals ranging from hundreds of millions to hundreds of billions of dollars, attracting clients worldwide.
Other large, well-known banks like Bank of America, Citigroup, and Deutsche Bank often land in Tier 2. Although they remain major players, they may not always lead the highest-profile transactions and sometimes must compete aggressively for business.
Elite Boutique Banks (Tier 1B):
Names like Evercore, Qatalyst, Centerview, and Perella Weinberg regularly rival bulge brackets in deal sophistication. These firms usually focus on M&A or restructuring, offer higher pay for junior staff, and may be chosen over bulge brackets by certain clients seeking specialized expertise.
Middle Market Banks:
Institutions in this category handle transactions typically valued in the tens of millions to a few billion dollars. Pay can still be competitive, but deals often involve smaller or mid-sized companies.
Regional and Boutique Banks:
Smaller firms with more localized networks can be stepping stones for career progression. The deal flow and pay vary widely based on the senior partners’ relationships and the industries they serve.
Financial professionals often weigh firm size and prestige against factors like team culture, sector focus, and potential for mentorship. While top-ranked banks provide name recognition and large-scale experience, the concentrated deal environment of a boutique can also accelerate growth.
What Investment Bankers Actually Do
Investment bankers function as intermediaries and advisors for major corporate decisions. Their core responsibilities revolve around mergers and acquisitions, and raising capital through equity (stock offerings, IPOs) or debt instruments (bonds, loans).
Advisory Services:
Bankers guide clients on valuations, strategy, and negotiations when buying or selling a company. Similar to real estate agents earning a commission on a home sale, investment banks receive fees for coordinating and finalizing these deals.
Advising on initial public offerings is another key task, where bankers help private companies determine valuation, file regulatory documents, and set share prices before going public.
Day-to-Day Work (Junior Level):
Financial Modeling: Constructing revenue forecasts, cash flow analyses, and valuation frameworks in Excel, often using multiple tabs and complex formulas.
Pitchbook Creation: Preparing PowerPoint presentations that summarize market data, deal rationale, and proposed transaction structures for client meetings.
Industry and Company Research: Reviewing filings and industry reports to produce insights that inform strategic recommendations.
Meeting Coordination: Liaising with senior bankers, legal teams, and clients to ensure all deal components move forward efficiently.
Teams frequently specialize in a particular industry (technology, healthcare, consumer products) or a product type (M&A, equity capital markets). This focus shapes the variety of deals you see, the complexity of your projects, and the expertise you develop.
❗Tip: If you find analyzing complex financial structures intriguing, or if you see yourself thriving in high-pressure, time-sensitive projects, investment banking may be a strong fit.
3. Hours and Lifestyle
Stories abound of analysts clocking 100-hour weeks, and while some are exaggerated, investment banking is demanding. Junior staff typically arrive at the office between 9 a.m. and 10 a.m. and may work until midnight or beyond, especially when deals intensify. Weekend hours can swing from zero in quieter periods to 20 or more during heated negotiations.
Why So Many Hours?
High Stakes and Tight Timelines: When a firm plans to go public or acquire another company, secrecy and speed are paramount. Only a handful of executives know about it, creating urgency for the bankers who handle logistics and analyses.
Constantly Evolving Data: A shift in client strategy or a new regulatory detail can force major revisions, meaning the latest version of a presentation or model always needs to be up to date.
Challenging Work Division: Building a single, complex financial model doesn’t always split easily among multiple people. The lead analyst must ensure consistency and accuracy, which can lead to late nights making changes solo.
Senior roles enjoy somewhat more predictable hours—associates might manage around 60-90 hours per week, while vice presidents and directors can maintain 50-80 or 40-60 hours respectively. Nonetheless, the nature of live deals means all team members should remain prepared for unplanned sprints.
4. Hierarchy and Compensation: Charting a Path to the Top
Investment banks generally follow a similar organizational ladder:
Analyst → Associate → Vice President → Director → Managing Director
Each promotion can occur in two- to three-year increments at the junior and mid-levels, though the leap from director to managing director could stretch to five years or more, hinging on performance and client wins.
Analyst Level
Entry salaries have climbed in recent years, often starting above $100,000. Bonuses can add significantly to total compensation, and the highest-paying elite boutiques may offer even more.
Associate Level
First-year associates often earn base salaries around $150,000 to $175,000, sometimes supplemented with stock grants at publicly traded banks. Bonuses can vault total pay well above $250,000.
Vice President and Beyond
Compensation escalates quickly once you reach the vice president tier, typically surpassing $500,000 annually, with top producers nearing or exceeding $1 million. Directors and managing directors regularly see seven-figure total compensation if they consistently bring in big deals and manage high-revenue relationships.
Though pay is a major draw, the journey demands substantial commitment. Alongside financial rewards, performance hinges on nurturing client relationships, managing complex negotiations, and leading teams effectively.
5. Pros and Cons of Pursuing Investment Banking
Investment banking offers substantial advantages for those who thrive in demanding, detail-oriented environments—but it isn’t a fit for everyone. Weigh the following points to determine whether it aligns with your career aspirations.
Pros
Access to High-Profile Deals: You’ll work on transactions that shape industries and may collaborate with top corporate leaders.
Rigorous Financial Training: Mastery of valuation, modeling, and strategic advisory skills translates well to many other finance or entrepreneurial ventures.
Impressive Exit Opportunities: Professionals often use their experience to transition into private equity, hedge funds, venture capital, or corporate development.
Competitive Compensation: Even at entry-level roles, salaries and bonuses can outpace those of other business fields, and pay scales rise steeply at higher ranks.
Cons
Demanding Hours: Maintaining 70–100-hour workweeks, particularly during live deals, leaves limited time for personal life.
Repetitive Transaction Structures: Mergers, acquisitions, and fundraisings can start to follow similar patterns over time, which may feel monotonous for some.
Less Operational Involvement: Unlike private equity or in-house corporate roles, investment bankers advise rather than oversee day-to-day business functions.
Always On-Call: Rapid response to emails and meeting requests is expected, even outside normal office hours.
For many, a few intense years in banking provide a springboard to more specialized or senior roles. Others find that the continuous rush of high-pressure dealmaking is exactly where they thrive.
6. Using Investment Banking Skills Beyond Traditional Roles
The analytical rigor and relationship-building capabilities honed in banking can prove invaluable across various business contexts. If you eventually decide to pivot, you’ll have a toolkit for assessing market opportunities, negotiating partnerships, and designing strategic growth initiatives.
Potential transition paths include:
Private Equity: Taking direct ownership stakes in companies and guiding their operational strategies.
Hedge Funds: Applying valuation and market analysis to complex trading or investment decisions.
Corporate Development: Steering mergers, acquisitions, and strategic planning within a single corporation.
Entrepreneurship: Leveraging your knowledge of capital markets to finance and scale your own startup.
Even for professionals who remain long-term, the intense early training can accelerate advancement, offering a deeper understanding of how capital shapes an organization’s strategic direction.
7. Tips for Evaluating if Investment Banking Is Right for You
Assess Your Tolerance for High Workload: Be honest about whether you can manage the long hours, tight deadlines, and immediate availability.
Consider Your Desired Skill Set: If modeling, valuation, and big-picture deal strategy excite you, the payoff can be substantial in building expertise.
Think About Future Trajectories: Banking is often a launchpad. If you’re aiming for private equity, hedge funds, or corporate leadership, the experience may prove invaluable.
Understand the Trade-Offs: Family life, personal pursuits, and leisure may take a back seat, particularly in the early years.
Ultimately, the job calls for consistent adaptability, communication, and stamina. If you relish intense collaboration and the challenge of guiding multi-million or multi-billion-dollar transactions, it can be an excellent match.
The Bottom Line
Investment banking stands at the crossroads of finance, strategy, and corporate leadership. Whether you’re drawn by the promise of significant compensation or the chance to influence transformative business deals, this career path offers exposure to high-profile transactions and global markets. Yet the demanding hours and repetitive deal structures present real challenges. By understanding these dynamics—from firm hierarchies to daily tasks and compensation trends—you can make an informed decision about whether this field aligns with your ambitions.
For those ready to embrace steep learning curves, investment banking can forge powerful connections and cultivate a skill set that paves the way for virtually any future in finance. Balancing its rigorous workload with its abundant opportunities, the experience shapes professionals who often excel in a broad range of subsequent roles, from private equity to C-suite leadership.
