Deloitte TS Interview: Common Questions and Answers

Prepare for the Deloitte Transaction Services interview with common technical questions, model answers and preparation strategies.

Published April 17, 2026· 3 min read

Deloitte's Financial Advisory practice is home to one of the most active Transaction Services teams in Europe. With strong presence across PE-backed deals, large-cap corporate M&A and infrastructure transactions, Deloitte TS is a highly competitive destination for deal-oriented finance professionals.

Deloitte Financial Advisory: Overview

Deloitte organises its deal work under the Financial Advisory umbrella, with TS sitting alongside:

  • Mergers and Acquisitions Advisory
  • Restructuring Services
  • Forensic and Dispute Services
  • Valuations and Modelling

The TS team handles financial and commercial due diligence, vendor due diligence and SPA support. It typically recruits from audit (internal transfers and external hires) and directly from business schools.

The Deloitte TS Interview Process

Candidates typically go through:

  1. Online application + situational judgement test (SJT)
  2. Video interview — pre-recorded, behavioural questions
  3. First-round technical interview — manager level, 45–60 minutes
  4. Case study exercise — on-site or virtual, based on a business scenario
  5. Final Partner interview — motivation, commercial outlook, leadership

Common Technical Questions and Strong Answers

"What is EBITDA and why do we use it in M&A?"

Strong answer: EBITDA removes the effects of financing structure (interest), taxation, and non-cash items (depreciation and amortisation), giving a proxy for the operational cash generation of the business. In M&A, it is used as the base for valuation multiples because it allows comparison across companies with different capital structures and tax positions.

"Walk me through the equity bridge."

Strong answer: Start at enterprise value — the agreed deal price. Deduct net financial debt (loans, finance leases, overdrafts, net of cash). Deduct debt-like items (pension deficit, restructuring provisions, deferred revenue). Adjust for the NWC target. The result is equity value — what shareholders receive.

"What would make you suspicious about a company's revenue?"

Strong answer: Concentration in a small number of customers, revenue recognised on long-term contracts that are not yet delivered, unusually high growth in the final months of the year, or revenue from related parties at non-arm's-length prices.

Deloitte-Specific Culture Points

  • Global mindset: Deloitte deals across borders. Showing interest in international M&A or cross-border transactions resonates well.
  • Technology: Deloitte has invested heavily in analytics tools. Mentioning data analytics skills or interest in technology-enabled diligence is valued.
  • Professionalism and presence: Deloitte interviewers assess executive presence — how you would present findings to a client board.

Preparation Recommendations

  • Practise narrating an EBITDA bridge verbally under time pressure
  • Review one recent Deloitte FDD thought leadership piece
  • Prepare strong answers for: "Why Deloitte?" and "Why TS specifically?"
  • Know the difference between buy-side and sell-side FDD

Conclusion

Deloitte TS rewards candidates who combine technical depth with commercial polish. The interview process is structured but gives plenty of opportunity to demonstrate both.
