Investment banking is known for its fast pace, high stakes, and grueling schedules. New hires often clock 80 to 100 hours each week, juggling meticulous financial modeling with delivering flawless client presentations. Despite the allure of big deals and early exposure to senior executives, these junior analysts and associates face intense pressure as they settle into their roles. Recent survey data provides an authentic glimpse into how they manage personal sacrifices, technical challenges, and fluctuating deal flow. By examining the experiences of individuals in their first few months on the job, it becomes clearer why this field commands such respect—and why it isn’t for the faint of heart. The survey also highlights varying levels of fulfillment, revealing both the hardships and rewards in a world few truly understand.
Many first-year analysts enter the role expecting long days, but they quickly learn how unpredictable those hours can be. Some report weeks as light as 35 hours when deal flow is minimal, while others find themselves consistently at 80 or more when multiple projects overlap. Based on a recent survey of new banking professionals, the average workload often hovers around 65 to 75 hours, with some outliers hitting beyond 100.
The massive range stems from a combination of inexperience and fluctuating assignments. When deadlines compress, junior team members may need to stay late or work weekends to finalize pitch books, update financial models, or respond to sudden client requests.
A slower week might appear out of nowhere, giving breathing room to recover physically and mentally.
During busy cycles, all-nighters can become unavoidable, especially if a deal is near completion.
⚠️Common Pitfall: Underestimating the intensity of investment banking schedules can lead to burnout. Building a reliable time-management system and recognizing personal limits can make these fluctuations more manageable.
2. The Toughest Challenges
Many new analysts emphasized that the steep learning curve can be as mentally taxing as the hours themselves. In addition to battling fatigue, they juggle the pressure to deliver immaculate work. Their commentary reveals a range of difficulties that arise almost immediately.
Maintaining Personal Relationships: One respondent lamented the inability to go on dates during the week, highlighting how high-pressure work can strain romantic or family ties. Partners may grow frustrated with canceled plans or constant phone-checking.
Attention to Detail: Small mistakes can erode trust. One banker shared feeling “pretty dumb” when a slip was found in a client deck. In an industry where presentations can command multimillion-dollar fees, associates and managers often expect perfection.
Industry Expertise: Keeping up with sector-specific knowledge is daunting. Bankers who handle biotech deals, for instance, might spend hours deciphering complex scientific terms only to realize they have barely scratched the surface. Without deep familiarity, it’s tough to provide strategic advice or impress more senior colleagues.
Lack of Formal Mentorship: Several newcomers noted that mentors can be scarce. Colleagues are often too busy to coach, leaving new bankers to fend for themselves. While analysts can learn faster under sink-or-swim conditions, the process can feel isolated.
⚡Important: Developing genuine industry knowledge isn’t optional. Clients look to bankers for insight that goes beyond spreadsheets. Even junior team members should carve out time to read sector reports, competitor analyses, and relevant news stories to bolster their expertise.
3. Navigating Steep Learning Curves and Attention to Detail
The banking environment demands near-perfect accuracy in everything from financial statements to PowerPoint decks. First-year hires frequently discover their work is reviewed in detail by senior bankers—every decimal and design element can come under scrutiny. This dedication to perfection can feel overwhelming, especially for those still mastering the technical basics.
Learning on the fly is a common experience. While junior bankers rely on existing templates and guidance from more experienced colleagues, they often have to fill knowledge gaps independently. Resources may be available, but time constraints can make thorough research difficult.
New analysts are expected to absorb sector-specific knowledge quickly to deliver relevant solutions.
One minor miscalculation in a model can create confusion for an entire deal team.
It can take months to develop the instincts needed for consistent, high-quality outputs.
❗Important: Remember that clients pay top fees for impeccable work. A small error in a presentation or a missing figure in a valuation can erode trust in the bank’s expertise.
4. Becoming an Industry Specialist
Technical prowess alone won’t suffice in investment banking—senior professionals also need a deep understanding of their chosen sector. Even at junior levels, demonstrating awareness of the market and its trends sets the groundwork for future promotions. Yet, carving out study time feels like a luxury when the workload piles up.
Healthcare teams, for instance, might evaluate biotech companies with complex scientific terms that challenge even those with strong academic backgrounds. In technology-focused groups, understanding the nuances of emerging software platforms or the competitive landscape is crucial for offering meaningful advice.
Reading sector reports, analyst notes, and market analyses can sharpen your perspective.
Scheduling brief daily blocks to review relevant news helps build credible industry knowledge.
Advanced levels of specialization become critical as you approach associate or VP roles.
📌Example: A first-year analyst covering energy companies who dedicates 15 minutes each morning to skim industry headlines may be better prepared to contribute meaningful insights during client calls or internal updates.
5. Limited Mentorship
One challenge repeatedly voiced by junior bankers is the scarcity of formal mentorship. While large financial institutions often promote diverse coaching initiatives, the reality on the ground can differ. With senior colleagues also working long hours, finding someone to offer consistent guidance can be a struggle.
Many survey respondents noted that they rely on informal support from peers. Swapping tips with another new analyst or seeking occasional direction from an associate might fill some gaps, but it doesn’t replace structured training. As a result, new hires often learn through trial and error, meticulously studying past client presentations and existing financial models to infer best practices.
Peer networks become essential in troubleshooting common obstacles and clarifying routine tasks.
Some groups form close-knit communities that share knowledge more freely, easing the steep learning curve.
High turnover among junior ranks can limit the availability of experienced mentors just one or two years ahead.
🔍Definition: Mentorship refers to a professional relationship in which an experienced individual (mentor) helps guide a less experienced person (mentee) toward success and growth through advice, knowledge-sharing, and support.
6. Building Mental Resilience and Confidence
New bankers often describe feeling tested on a daily basis—both mentally and emotionally. The pressure to deliver precise work under tight timelines can be stressful, but it also fosters rapid professional growth. Over time, repetition of tasks like structuring presentations or updating valuation models can boost proficiency and confidence.
Some find it unnerving to constantly apologize for overlooked details or misjudged assumptions, especially for those accustomed to excelling academically. A few months in, the job’s complexity becomes clearer, and analysts often adapt by improving their workflow, seeking feedback earlier, and clarifying assignments to reduce rework.
Continual learning can feel rewarding once initial nerves settle.
Adaptability is key: a missed final check may lead to corrections, but it also highlights areas for immediate improvement.
Networking with peers helps alleviate stress, reminding new bankers that none of them have all the answers from day one.
7. Gauging Fulfillment in the Early Stages
Job satisfaction varies widely among first-year bankers. Some struggle with repetitive tasks or feeling like they’re on “training wheels,” waiting to prove themselves. Others find the role deeply gratifying, citing opportunities to learn from CEOs and CFOs and the chance to contribute to significant transactions even at a junior level.
Individual expectations matter. Those who prioritize professional growth may appreciate the steep learning curve, despite the stress. On the other hand, individuals seeking an immediate sense of impact may find the role more frustrating. Many new bankers realize they’re building a skill set that can open doors to other finance verticals or corporate roles in the future.
A supportive deal team can enhance fulfillment by celebrating milestones, however small.
Recognizing that not every transaction is glamorous helps manage expectations around the daily grind.
Some bankers eventually shift to private equity or corporate development once they’ve established solid credentials in this demanding environment.
🚀Fast Fact: In a global survey, a majority of junior bankers reported they felt more prepared for subsequent career moves after their initial 12 months, largely due to steep on-the-job learning.
The Bottom Line
The experiences shared by these new investment banking professionals highlight a world that is as intellectually challenging as it is physically and mentally demanding. Work hours can soar well into triple digits in peak seasons, leaving personal routines and social calendars in disarray. Meanwhile, the need for perfection tests patience, confidence, and humility on a daily basis.
Despite the difficulties, many analysts ultimately appreciate the invaluable skills and professional depth they acquire during these formative months. The ability to tackle complex financial tasks under pressure, grasp specialized industry knowledge, and interact with top executives sets the stage for long-term career advancement. By acknowledging the realities of the role—high expectations, intense scrutiny, and sporadic mentorship—new bankers stand a better chance of thriving. Charting a successful path often means embracing both the highs and lows, turning each challenge into a stepping stone for future opportunities.
