Platform Portfolio Support interview prep.

Behavioural questions to expect

1. Walk me through your CV.
2. Walk me through the engagement or project you're most proud of.
3. Tell me about a weakness, a failure, or feedback you've received and worked on.
4. Why the operating-partner / portfolio-ops seat — and why not stay in consulting, industry, or move to the deal team?
5. Why the firm?
6. Which the sector portfolio companies would you most want to work with, and why?
7. How would you describe the firm's operating-partner model in your own words?
8. How does the operating-partner function create value for the firm's LPs?

Technical concepts to master

• The canonical first-100-days playbook

  Days 1-14 — Listen + diagnose · Days 15-45 — Co-design the VCP with the CEO + CFO · Days 46-80 — Quick wins for credibility · Days 81-100 — Board lock + bonus alignment · Ongoing — CEO + board governance

• EBITDA bridge + exit-readiness discipline

  EBITDA bridge (entry → exit) · Quality of Earnings (QofE) at exit · Run-rate vs reported EBITDA · Lever attribution methodology

• LBO fundamentals — capital structure and returns

  LBO structure · Returns drivers — the three sources · Capital structure — debt tranches · Paper LBO — the simplified math · Cash flow available for debt repayment

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
