Company Summary
One Capital Advisory is a South African independent advisory and investment banking firm headquartered in Johannesburg. The firm specialises in mergers and acquisitions, equity capital markets, debt advisory, structured finance, and corporate finance transactions across a range of sectors including financial services, resources, infrastructure, and industrials. As an independent advisory house — not attached to a large commercial bank — One Capital operates at the deal-making end of South African corporate finance, advising listed companies, private equity firms, government entities, and high-growth businesses on complex, high-value transactions.
Working at One Capital means being close to live deals from the very beginning of your career. Unlike graduate programmes at large banks where you may spend months in training rotations before touching real work, an advisory firm of this size and focus puts graduates directly into transaction teams — meaning the learning curve is steep, the exposure is immediate, and the career development is accelerated. For a quantitatively strong graduate with ambitions in investment banking, corporate finance, or financial advisory, this is one of the most direct entry points available in South Africa.

Key Requirements
- Completed degree in one of the listed fields from a recognised South African university
- Strong academic record — investment banking and advisory firms are highly selective; a strong GPA or cumulative average is important

- High attention to detail — errors in financial models or client documents are not acceptable in this environment

- Proficiency in Microsoft Excel and PowerPoint — advanced Excel skills are a significant advantage

What You Will Learn
A graduate traineeship at an independent advisory firm like One Capital offers exposure that most graduates in large institutional programmes simply do not get at this stage of their careers:
- Financial modelling — building, stress-testing, and presenting detailed financial models for mergers, acquisitions, valuations, and capital raises. Excel proficiency will go from good to exceptional within months
- Valuation methodologies — learning and applying Discounted Cash Flow (DCF) analysis, comparable company analysis, precedent transaction analysis, and sum-of-the-parts valuations on real South African and African transactions
- Transaction execution — supporting live M&A, debt, and equity deals from initial mandate through to closing, including due diligence coordination, information memorandum preparation, and client communication
- Sector research — producing deep-dive research on industries, companies, and markets to support pitch books and transaction mandates
- Client interaction — attending client meetings, presenting analysis, and building relationships with CFOs, CEOs, and financial directors of major South African companies at a stage in your career when most graduates are still in classroom rotations
- Regulatory and deal structuring knowledge — understanding JSE Listings Requirements, Companies Act provisions, and the regulatory frameworks that govern South African corporate transactions
- Presentation and communication skills — producing boardroom-quality pitch books, deal summaries, and investment committee presentations under real time pressure
- Professional network — working alongside experienced dealmakers, building a network across corporate South Africa that will serve your entire career
Possible Interview Questions
Investment banking and advisory interviews are known for being rigorous. Prepare thoroughly for both technical and behavioural questions:
Technical Questions
- Walk us through a Discounted Cash Flow valuation — what are the key inputs and what are the main limitations of this methodology?
- What is EBITDA and why is it commonly used in transaction valuation multiples?
- If a company has a Price-to-Earnings ratio of 15, what does that tell you about how the market values it relative to its earnings?
- What is the difference between enterprise value and equity value, and how do you move between the two?
- You are given three years of financial statements for a South African listed company. Walk us through how you would begin to analyse the business.
- What is the current prime lending rate in South Africa, and what impact does it have on corporate valuations?
Behavioural Questions
- Tell us about the most analytically complex project or assignment you completed during your degree — what made it difficult and how did you approach it?
- Describe a situation where you had to produce high-quality work under significant time pressure. How did you manage it?
- Why corporate advisory specifically — and why One Capital rather than a large investment bank?
- Where do you see your career in financial services five years from now?
Tip: Read the financial press before your interview. Know what is happening in South African M&A markets, what major deals have been announced recently, what the JSE has been doing, and what the macroeconomic environment looks like. Candidates who can speak intelligently about the real deal landscape — not just textbook theory — immediately demonstrate that they are serious about this career path. BusinessDay, Moneyweb, and the Financial Mail are your starting points.
Career Advice
- Independent advisory is a different world from retail and commercial banking — understand the distinction before you apply. One Capital does not take deposits, lend money, or manage retail customer accounts. It advises corporate clients on transactions. If what excites you is deal-making, financial structuring, and working at the intersection of finance and corporate strategy — this is your environment. If you are drawn to retail banking, wealth management, or insurance, look elsewhere and apply your energy honestly.
- Excel is not optional — it is a survival skill. Investment banking analysts spend enormous amounts of time in Excel building and maintaining financial models. Before you join, your Excel skills should include advanced formulas, pivot tables, data tables, scenario analysis, and ideally some exposure to financial modelling conventions. Free and paid financial modelling courses are available online — complete one before your interview if you can.
- Your degree is your entry ticket — your attitude determines your ceiling. Graduate trainees who succeed in advisory firms are those who show up early, stay late when deals demand it, ask intelligent questions, volunteer for tasks beyond their job description, and treat every piece of work — however small — as if a client’s board is about to read it. That mindset, sustained consistently, is what separates analysts who get promoted from those who do not.
- For Actuarial Science and Financial Mathematics graduates: Your quantitative training is exceptionally well suited to financial modelling, risk analysis, and structured finance. You may find that your ability to build and interrogate complex numerical models sets you apart from accounting and commerce graduates in the programme. Lean into that strength deliberately.
- For Engineering graduates: The inclusion of engineering in the eligible fields is deliberate. Structured analytical thinking, quantitative rigour, and the ability to break down complex systems — all core engineering skills — translate very well into financial modelling and transaction analysis. Infrastructure, mining, and energy transactions in particular benefit from engineers who understand the underlying assets. Frame your application around these transferable strengths.
- For Accounting and Management Accounting graduates: Your understanding of financial statements, cost structures, and accounting standards gives you a foundation that pure finance graduates sometimes lack. Focus on demonstrating that you can move from accounting knowledge to financial analysis and commercial judgement — that transition is what advisory work requires.
- Build your knowledge of the South African deal landscape actively. Subscribe to BusinessDay and Moneyweb. Follow the JSE regulatory news feed for announcements of listed company transactions. Read the annual reports of South African companies you find interesting. The candidates who walk into One Capital interviews knowing which deals are live, which sectors are active, and what is driving M&A activity in South Africa right now will be remembered long after the interview ends.
- Closing date is 31 August 2026 — but do not wait until August. Advisory firms often fill graduate positions on a rolling basis as strong candidates are identified. Early applications from well-prepared candidates are always noticed. Submit as soon as your documents are ready.
