Multi-Mentor Models Are Changing the Finance Career Coaching Game
London,UK – September 15, 2026 – Finance career coaching has traditionally suggested a simple relationship: one student, one coach. But that model becomes harder to maintain as finance recruiting becomes more specialized. Preparing for investment banking is different from preparing for private equity, hedge funds, or quantitative finance. Even within investment banking, what a student needs to know can change by industry, group, and stage of recruiting. The person best equipped to teach accounting and valuation may not be the person best equipped to explain an industry, pressure-test a stock pitch, or simulate a final-round interview.
One Strategy Group, or OSG, has built its finance career coaching around a different model. Rather than relying on one coach throughout the process, students can interact with over 30 different mentors, with specialists brought in as their needs change. The number itself is less important than the idea behind it: finance recruiting has become specialized enough that preparing for it may require specialized coaching as well.

The mentor changes when the problem changes
Early finance career preparation can begin broadly. Students may need to explore career paths, build resumes, find early internships, and develop foundational skills. Once a student decides to pursue investment banking, the preparation becomes more specific. Candidates need accounting and valuation knowledge, but they also need industry expertise, behavioral interview preparation, networking strategy, and an understanding of current transactions and markets.
That industry knowledge can look very different by vertical: TMT candidates may need to understand recurring revenue models, software metrics, and AI investment trends; healthcare candidates may encounter biotech valuation, drug pipelines, and regulatory developments; energy candidates may need familiarity with commodity prices, reserve-based valuation, and the energy transition; and industrials candidates may be expected to understand cyclicality, supply chains, and infrastructure spending.
Move outside investment banking, and the differences become larger. Private equity interviews can involve cases and investment judgment, hedge fund recruiting can require stock pitches and market views, and quantitative finance can test mathematics, probability, coding, and problem-solving. One coach may understand finance recruiting broadly, but maintaining deep expertise across all of those areas is a different challenge.
OSG uses a roughly 1:30 student-to-mentor model, with different specialists covering technical skills, industry knowledge, behavioral interviews, networking, and specialized interview preparation. A student might first work with someone on accounting, valuation, and investment banking technicals, then move to an industry specialist who can help them understand the sector they are targeting. Another mentor may focus on networking or behavioral interviews, while later preparation can involve professionals familiar with the type of interview the student is likely to encounter. The objective is not to give students as many opinions as possible, but to match the expertise to the problem.
That distinction matters because students rarely have identical weaknesses. One candidate may understand valuation but struggle to communicate clearly. Another may interview well but lack industry knowledge. A third may have strong technical skills but struggle when an interviewer challenges an investment thesis. The usefulness of a multi-mentor model depends on identifying which problem is actually holding the student back.
More mentors only work if they provide different expertise
More mentors do not automatically produce better preparation. Without structure, more voices can create conflicting advice. OSG says its students have accumulated more than 3,500 offers across its programs over the past seven years, representing recruiting processes across different universities, backgrounds, roles, offices, and groups. Those outcomes have been used to build a proprietary recruiting database that tracks how the process differs by university, region, office, and role. Combined with input from professionals currently working across finance, that information allows OSG to build a more customized recruiting strategy around each student’s specific targets, including details that are often difficult to find through public recruiting resources.

A student who already understands investment banking technicals may gain little from another introductory accounting lesson. The bigger gap may be industry knowledge or communication under pressure. Someone pursuing an investing role may need less time memorizing technical questions and more time defending an investment thesis. The multi-mentor model works only when different mentors are solving different problems.
Hedge fund recruiting provides a clearer example of why different perspectives matter. Fundamental investing roles tend to emphasize deep company and industry analysis, while L/S Equity roles place greater emphasis on forming and defending long and short investment theses. In both, candidates need a strong foundation in accounting and valuation, but interviews place greater weight on judgment and business acumen. The harder question is whether a candidate can think like an investor: identify what matters in a business, weigh competing information, form an independent view, and defend it under pressure. Those skills are difficult to develop from a textbook or interview guide alone. They are built over time by discussing companies and markets with experienced investors, hearing different perspectives, and gradually developing an investment perspective of one’s own.
For one student preparing to interview with one of the world’s leading hedge funds, OSG arranged for 14 experienced investors to repeatedly critique and refine the student’s stock pitches. Different investors challenged the thesis from different perspectives, forcing the student to understand the argument well enough to defend it when assumptions changed. The point was not to teach 14 versions of the same answer. It was to expose the candidate to 14 different ways that answer could be challenged.
Different interviewers expose different weaknesses
The same principle applies to investment banking interview prep. Accounting and valuation provide a common technical foundation, but interviews can become more specific as candidates progress. Industry groups may expect students to discuss relevant transactions, market developments, and sector dynamics, while individual interviewers can emphasize very different parts of a candidate’s preparation.
A student who practices exclusively with one coach can also become accustomed to that person’s questions and interviewing style. One real interviewer may push on technicals, another may focus on industry knowledge, and another may spend most of the conversation testing communication and judgment. OSG uses repeated mock interviews, including in-person simulations at their New York headquarters designed to approximate final-round investment banking interviews. Rotating interviewers makes those repetitions less predictable and forces students to apply what they know rather than memorize how one coach wants them to answer.
The case for a multi-mentor model ultimately comes from finance recruiting itself. A student can move from career exploration to accounting and valuation, networking, industry specialization, behavioral preparation, and final-round interviews within one investment banking recruiting cycle. Students exploring private equity, hedge funds, or quantitative finance face additional skills and interview formats. It is difficult for one person to be the best source of expertise at every stage.
That does not make the student’s role smaller. A mentor can teach valuation, explain an industry, critique a stock pitch, or conduct a mock interview. When the actual interview begins, the student still has to perform. The value of having 30 mentors is not having 30 people tell a student what to do. It is having access to the right expertise when the problem changes.
