Key Responsibilities

### Daily responsibilities (most frequent)

  • Build and update financial models (30–40% of day): Create and maintain 3-statement models, DCFs, and simple LBOs in Excel. Ensure inputs (revenue growth, margins, capex) reconcile with management forecasts. Accurate models speed up senior bankers' decision making and increase win rates on pitches.
  • Prepare client deliverables and pitch materials (20–30%): Design pitch books, CIM sections, and info memoranda using PowerPoint. Include 35 year forecasts, comparable company tables, and transaction comps. High-quality deliverables improve credibility in client meetings.
  • Conduct market and sector research (10–15%): Pull data from Bloomberg, Capital IQ, and industry reports to support valuation assumptions and deal rationale. Provide 34 key insights per client brief that influence valuation ranges.

### Weekly responsibilities

  • Due diligence support and documentation (weekly): Coordinate with lawyers, accountants, and client teams to gather contracts, financial statements, and cap tables. Track outstanding items in a weekly checklist to keep timelines on a 48 week sell-side process.
  • Deal execution tasks (weekly): Assist in drafting term sheets, SPA exhibits, and management Q&A. Run sensitivity analyses (±250 bps revenue; ±100 bps margin) to show deal impact under different scenarios.

### Strategic / periodic responsibilities

  • Client and internal communication (periodic): Join client calls, take detailed minutes, and follow up with action items within 24 hours. This builds trust and keeps processes moving.
  • Process improvement (monthly/quarterly): Propose one workflow or template change each quarter (e.g., standardized model tabs) to reduce model prep time by at least 15%.

Actionable takeaway: Prioritize accurate modelling and clear client materials; track tasks with checklists and propose one efficiency improvement every quarter.

Required Qualifications & Skills

### Technical skills (must-haves)

  • Advanced Excel: Fast with formulas, pivot tables, and macros. Use Excel daily to build 3-statement models and run sensitivity tables that inform valuation ranges.
  • Valuation techniques: Comfortable with DCF, comparable company analysis, and precedent transactions. Apply these on 35 live assignments per quarter.
  • PowerPoint and presentation design: Turn data into 1020 slide client decks that highlight key metrics and recommendations.
  • Data sources: Experience using Bloomberg, Capital IQ, PitchBook, or Refinitiv to pull market multiples and comparable transactions.

### Soft skills

  • Clear written communication: Draft concise client emails, investment memos, and meeting notes. Seniors rely on your summaries to brief clients.
  • Attention to detail: Spot reconciliation errors, ensuring models balance and footnotes are consistent; this reduces revision cycles by an estimated 20%.
  • Time management: Handle multiple tasks with weekly deadlines; prioritize to meet deal milestones.
  • Teamwork: Collaborate with associates, analysts, and external advisers to close deals on time.

### Education & certifications

  • Bachelor’s degree in finance, accounting, economics, or related field (must): Provides core valuation and accounting knowledge.
  • CFA Level I or progress toward CFA (nice-to-have): Demonstrates commitment to investment knowledge and ethics.
  • Accounting coursework or CPA candidate status (nice): Helpful for complex due diligence and financial statement adjustments.

### Experience requirements

  • 0–2 years in investment banking, corporate finance, or transaction advisory (must): Familiarity with live deal processes, modelling, and client deliverables.
  • Internships on live deals (nice-to-have): One or more internships where you supported at least one completed transaction.

Actionable takeaway: Focus on Excel and valuation skills, gain exposure to live deals through internships, and document your impact with examples (models built, decks prepared, deals supported).
