"Why investment banking?" is asked in virtually every IB interview. It sounds simple, but most candidates blow it—either giving generic answers that apply to any finance job or revealing motivations that make interviewers cringe.
Here's exactly how to answer it.
What They're Really Asking
When an interviewer asks "Why investment banking?", they're actually asking several questions:
- Do you understand what the job actually is? (Many candidates don't)
- Are your motivations sustainable? (Will you quit in 6 months when it's hard?)
- Have you tested your interest? (Or is this theoretical?)
- Are you going to say something that makes me not want to work with you?
Your answer needs to address all four.
The Framework That Works
Structure your answer in three parts:
Part 1: The Spark (What Drew You In) A specific experience or moment that triggered your interest. This grounds your answer in reality.
Part 2: The Confirmation (How You Tested It) What you did to explore and validate that interest. This shows intentionality.
Part 3: The Fit (Why IB Specifically) What about investment banking—as opposed to consulting, corporate finance, or other paths—makes it the right fit.

What TO Say
Mention these elements: - Exposure to deals, transactions, or M&A that sparked interest - Specific aspects of IB that appeal: deal execution, client advisory, financial analysis - Evidence of testing your interest (internships, projects, coursework) - Intellectual curiosity about how deals work - Desire for steep learning curve and high-intensity environment
Good motivations: - "I want to understand how businesses are valued and transactions are structured" - "I thrive in fast-paced environments with high stakes" - "I want to build technical skills that compound over a career" - "I'm drawn to working on consequential projects that shape industries"
What NOT to Say
Never mention: - "Exit opportunities" (Everyone knows you want to leave for PE—don't say it) - "Money" (Obvious and makes you seem mercenary) - "Prestige" (Shallow and signals you don't understand the work) - "I want to do deals" (Vague—what do you think deals involve?)
Avoid these framings: - "I've always wanted to work on Wall Street" (Why? Be specific) - "I love finance and numbers" (So do accountants) - "I want to help companies grow" (You could do that in consulting or corporate)
Example Answers by Background
For a Target School Junior
"My interest in investment banking started sophomore year when I joined the Investment Banking Club and worked on a stock pitch competition. Breaking down a company's financials and thinking through its valuation got me hooked on the analytical process. Last summer, I interned at [Bank/Firm] where I worked on pitch materials for a potential acquisition. Seeing how the team structured the analysis and advised the client confirmed that I want to be on the deal side—not just analyzing companies theoretically, but working on live transactions with real stakes. What draws me specifically to banking over other paths is the combination of technical depth and client exposure. I want to build those modeling and valuation skills while also learning how to advise executives on critical decisions."
For a Non-Target with Limited Finance Experience
"I became interested in investment banking through an unexpected path. I was working on a financial analysis project in my accounting class, and I started reading about how the company we analyzed had just been acquired. I went down a rabbit hole learning about the deal—the valuation, the strategic rationale, the process—and realized this was the type of work I wanted to do. Since then, I've focused on building relevant skills: I completed Wall Street Prep's financial modeling program, joined our finance club, and completed an internship in corporate finance where I worked on budgeting and some basic valuation work. Those experiences confirmed my interest, but I want to work on larger, more complex transactions. Investment banking offers the opportunity to build those skills quickly while working on deals that actually move markets."
For a Career Changer / Lateral
"I came to investment banking from [Previous Industry], where I was doing [Role]. While I enjoyed [aspect], I found myself increasingly drawn to the financial and strategic aspects of decisions. Last year, I had the opportunity to work closely with our investment bankers during a financing round, and I saw firsthand how they structured the process and advised our leadership. That experience crystallized something I'd been thinking about: I want to be the advisor in the room, not just the operator. I know the transition is challenging, but my background gives me sector knowledge in [Industry], and I've spent the past [X months] building the technical foundation through [coursework/certifications]. Banking is the right path because it combines analytical rigor with strategic advisory work in a way that other roles don't."
Common Follow-Up Questions
"Why not consulting?" > "I considered it, but I'm more interested in financial analysis and transaction execution than operational strategy. Banking offers deeper exposure to valuation, capital markets, and deal structuring."
"Why not private equity directly?" > "I want to build the technical foundation first. Banking provides the modeling skills and deal exposure that make someone effective in investing roles. I believe in earning that foundation."
"What if you hate the hours?" > "I've talked to enough analysts and associates to understand what the lifestyle looks like. I'm not naive about it, but I'm also motivated by working on meaningful transactions, and I perform well in high-intensity environments."
