Big 4 Transaction Services Interview Tips
Practical tips for passing a Transaction Services interview at EY, PwC, KPMG or Deloitte: technical preparation, common mistakes and what makes a strong candidate.
Interviewing for Transaction Services at one of the Big 4 is competitive. The technical bar is higher than for equivalent audit roles, and recruiters are good at distinguishing candidates who have studied from candidates who have actually understood the material. Here's what actually helps.
Understand the difference between TS and audit
If you're coming from an audit background, the most important shift is conceptual. Auditors ask: "Are the accounts correct?" Transaction Services professionals ask: "Does the reported performance reflect the sustainable earning power of this business?"
The answer to the second question requires judgment, context and an understanding of what drives value in a deal — not just technical compliance. Make this shift visible in your answers from the very first round.
Master the EBITDA bridge before anything else
Every Big 4 Transaction Services interview will test your understanding of the EBITDA bridge. You should be able to:
- Define each layer (one-offs, run-rate, pro-forma) and explain the difference.
- Give three concrete examples of adjustments at each level.
- Explain what makes a strong adjustment vs a weak one (documentation, recurrence test, economic logic).
- Construct a simple bridge from a P&L extract on the spot.
If you can do all four fluently, you're ahead of 80% of candidates.
Know the key balance sheet topics
Beyond the P&L, interviewers test:
- Net debt: all components, including debt-like items (unfunded pensions, earn-outs) and cash-like items.
- Working capital normalisation: NWC peg, seasonality, DSO/DPO/DIO.
- EV to Equity bridge: end-to-end mechanics with real examples.
You don't need to be a balance sheet expert, but you need to be comfortable navigating these concepts under pressure.
Prepare five transaction-specific words
Arrive speaking the language of the deal: locked box, completion accounts, earn-out, data room, request list, signing, closing, SPA. Using these terms naturally signals professional awareness.
Do your homework on the specific team
Before any interview at EY, PwC, KPMG or Deloitte, research:
- The sectors covered by the local TS team.
- Any recent transactions they advised on (check M&A press releases).
- The team size and structure (linked in to find analysts and managers).
One precise reference to their activity in the interview goes further than five generic statements about the firm.
The interview trap most candidates fall into
Giving textbook definitions without any economic context. "Quality of Earnings is an analysis of the recurring profitability of a business" is a textbook definition. The interview-winning version adds: "It matters because buyers price companies on an EBITDA multiple — if that EBITDA is overstated by EUR 500k and the multiple is 8x, the overvaluation is EUR 4m. The QoE is how you prevent that."
