Platform Portfolio Support interview prep.

Has sat across from the CEO + CFO of a newly-acquired portfolio company on day 1 with a value-creation plan and a 4-year exit clock running.

What interviewers look for

  • Can the candidate name the value-creation levers cold AND say which ones are typically worth what, pricing usually 3-7% EBITDA uplift, procurement 2-5%, operational excellence 5-15%, not just list them.
  • Does the candidate think like an OPERATOR (in the business, hands on the P&L, measurable EBITDA by month-end), not a CONSULTANT (slides, frameworks, hand-off)? The voice difference is the most common rejection reason.
  • Does the candidate understand the CEO dynamic, you advise, the CEO decides, you escalate to the board only when truly needed, not 'I would direct the CEO'?
  • Can the candidate write a 100-day plan in real time: diagnose, prioritise 3-5 levers, set up the operating cadence, secure quick wins, build credibility?
  • Does the candidate carry quantitative impact on their CV, $X EBITDA delivered, Y% margin uplift, Z working-capital days released, not just project names?
  • Does the candidate think exit-back: every lever pulled today must be defensible in a QofE + bankable in the exit-multiple thesis, not a one-time benefit that won't survive diligence?

Behavioural questions to expect

  1. Walk me through your CV.

    What it tests: Story coherence + OP-relevant operating chops. The interviewer wants evidence of OPERATING work (line management, P&L ownership, transformation delivery), not consulting deliverables. The cardinal CV failure is a pure-consulting / pure-banking story without ANY operating evidence.

  2. Walk me through the engagement or project you're most proud of.

    What it tests: Depth of ownership + ability to articulate measurable impact + the operator voice. Interviewers screen out candidates who narrate analysis without landing on dollars-on-the-P&L. The MY VIEW beat at the end is what separates an OP candidate from a consulting candidate.

  3. Tell me about a weakness, a failure, or feedback you've received and worked on.

    What it tests: Self-awareness + ability to take a real critique without deflecting. For an OP seat, real OP failures are visible: a CEO relationship that turned, a lever that didn't deliver and you missed the early signal, a 100-day plan that was too ambitious and broke the management team. Candidates who give fake weaknesses downgrade.

  4. Why the operating-partner / portfolio-ops seat, and why not stay in consulting, industry, or move to the deal team?

    What it tests: Authentic fit for the OP seat specifically. Interviewers can tell within 30 seconds whether the candidate has thought through the trade-off vs (a) staying in consulting (more variety, less ownership), (b) staying in industry (deeper ownership, less variety), (c) going to the deal team (more capital allocation, less hands-on). Generic 'I love value creation' answers downgrade.

  5. Why this firm?

    What it tests: Whether the candidate has done the homework on the firm's portfolio + OP model. The interviewers hear generic 'great platform' answers 10 times a week.

  6. Which the sector portfolio companies would you most want to work with, and why?

    What it tests: Whether the candidate understands what makes a sector workable as an OP, not just 'I find it interesting'. The right answer demonstrates sector-specific lever literacy.

  7. How would you describe this firm's operating-partner model in your own words?

    What it tests: Whether the candidate has internalised HOW the firm runs value creation, not just what the website says. Tests homework depth + judgment about which model matches the candidate's style.

  8. How does the operating-partner function create value for this firm's LPs?

    What it tests: Whether the candidate understands the OP function commercially, every dollar of OP cost has to deliver multiple dollars of EBITDA at exit. Tests whether the candidate thinks about the OP function as a P&L, not just a support service.

Technical concepts to master

The canonical first-100-days playbook

Days 1-14. Listen + diagnose
Spend a week IN the business, site visits, ride-alongs, top-15 employee 1:1s, top-10 customer + top-10 supplier calls. Pull the QofE + commercial DD + management reporting pack and build a working hypothesis tree.
Days 15-45. Co-design the VCP with the CEO + CFO
Crystallise 3-5 priority value-creation levers, each sized ($X EBITDA, timing, risk), each with a named lever-owner from the management team. Set up the operating cadence (MBR, KPI dashboard, value-creation steering committee).
Days 46-80. Quick wins for credibility
Secure 2-3 visible early wins (a pricing move, a procurement renegotiation, a working-capital release) to build credibility with the management team + the board.
Days 81-100. Board lock + bonus alignment
Present the diagnosed value-at-stake + the 3-5 priority levers + the cadence + early wins to the board. Lock the management team's bonus plan to VCP milestones.

EBITDA bridge + exit-readiness discipline

EBITDA bridge (entry → exit)
Decomposition of EBITDA growth from entry to exit across canonical sources: organic revenue growth, pricing, gross-margin expansion, opex efficiency, bolt-on M&A contribution, one-time / run-rate adjustments.
Quality of Earnings (QofE) at exit
Independent accounting diligence at exit that scrutinises every adjustment to reported EBITDA: run-rate adjustments, one-time costs, pro-forma synergies, pricing that hasn't fully landed.
Run-rate vs reported EBITDA
Reported EBITDA is the actual LTM number; run-rate EBITDA is the annualised version of the latest quarter (or month), reflecting the trajectory rather than the historic average.
Lever attribution methodology
Discipline of attributing every $ of EBITDA growth to a named lever (pricing realisation, procurement save, headcount efficiency, M&A) tracked monthly through the value-creation steering committee.

LBO fundamentals, capital structure and returns

LBO structure
Acquire a company using a high % of debt and a small % of equity. Use the target's cash flows to pay down debt; exit in 3-7 years for returns via equity appreciation.
Returns drivers, the three sources
(1) EBITDA growth (operational improvement + organic growth), (2) Multiple expansion (exit at higher multiple than entry), (3) Debt paydown (deleveraging).
Capital structure, debt tranches
Multiple debt layers with different priorities, rates, and terms. Senior secured (revolver, term loan A/B) → unsecured (high yield) → subordinated → mezzanine → equity.
Paper LBO, the simplified math
Mental model: entry EV, debt/equity split, project EBITDA growth + debt paydown, exit at assumed multiple, compute MoM and IRR.

Practical drills

  • We've just closed on a $400M-EV portfolio company in the sector. The CEO is staying. Walk me through your first 100 days. You have 7 minutes prep + 5 minutes delivery + expect probing.
  • A services portfolio company has $300M revenue, $40M EBITDA (13% margin), 5% organic growth, 200 customers with the top 20 driving 60% of revenue. The firm's deal thesis is 2.5x MoM in 4 years. Walk me through how you'd build the VCP and which 3-4 levers you'd prioritise.
  • Your portfolio CEO disagrees with you on a pricing transformation you believe is worth 4 points of EBITDA. The CEO thinks it will damage anchor-customer relationships. Walk me through how you handle.

Smart-question anchors

  • OP team structure + reporting line, centralised vs sector-aligned vs deal-team-embedded, and how OPs are matched to portfolio companies
  • Engagement model, secondment vs part-time advisory, typical CEO + CFO interaction cadence, and depth of OP involvement
  • Value-creation philosophy, top-down playbook vs bottom-up VCP, named methodology, and how the firm reports value creation to LPs
  • OP-to-deal-team dynamic, how OPs feed into deal sourcing, diligence, and exit planning, and how disputes get resolved
  • Career path + development, partner-track for OPs, lateral moves into deal team or portfolio CEO seats, and stated development model
