A realistic timeline for a Financial Due Diligence engagement, from kick-off to final report, with milestones and what analysts do at each stage.
One of the most useful pieces of context for a TS interview candidate is understanding how long FDD actually takes, and what happens at each stage. The timeline varies by deal size and complexity, but the structure is broadly consistent.
| Deal Size | Typical FDD Duration |
|---|---|
| Small (EV <€30m) | 2–3 weeks |
| Mid-market (EV €30m–€200m) | 3–5 weeks |

| Complex / cross-border | 8–12 weeks |
