Each year, the Big 4 (Deloitte, EY, KPMG, PwC) hire several thousand interns and graduates in audit across France. Given this volume, the motivation interview is largely standardized — which means it can be prepared methodically, provided you know the expected format.
What the Big 4 assess in a motivation interview
Unlike a technical investment banking interview, the audit motivation interview tests little to no financial modeling knowledge. Recruiters mainly assess:
- A genuine understanding of the auditor role, including its constraints (heavy seasonality, client-site travel, high case volume), not just its prestige
- Motivation for the specific firm, beyond "the Big 4 in general"
- Soft skills: rigor, teamwork ability, and pressure management during the busy season (January-April)
- Consistency of your career project, even if audit is only a stepping stone toward other roles (transaction services, management control, corporate finance)
Each firm publishes its own presentation of audit careers: EY presents its auditor path 🔗, PwC details its financial audit engagements 🔗, KPMG lists its audit openings 🔗, and Deloitte explains its hiring process 🔗. Reading these beforehand is essential to avoid generic answers.
The most common questions
"Why audit?" The number one question, almost always asked. A strong answer connects a concrete fact (internship, coursework, academic project) to a specific aspect of the role: the diversity of auditable sectors, the methodological rigor, or the accelerated training audit offers early in a career.
"Why this firm and not another?" Avoid "you're the market leader" (true for all 4 firms, so it carries no differentiating value). Lean instead on company culture, a specialization sector, or feedback from someone already working there.
"How do you handle a high-pressure workload period?" Busy season (January to April) means long weeks. The recruiter wants to confirm you're aware of this and have already shown you can sustain the pace (an intensive internship, an exam period, extracurricular activity alongside your studies).
"Describe a situation where you showed rigor." Pick one precise example with a measurable outcome, rather than a statement of intent.
Structuring your answer on choosing audit
A convincing answer generally follows three steps:
- The trigger: a concrete fact explaining your interest (internship, accounting coursework, meeting a professional)
- What you expect from it: the diversity of engagements, structured training early in your career, exposure to multiple industries
- The path forward: even without absolute certainty, show you've thought about a 3-5 year horizon (sector expertise, transaction services, moving into corporate finance)

Common mistakes
- Not distinguishing external audit (Big 4) from internal audit (in-house): two different jobs, don't confuse them in the interview
- Answering purely in terms of pay or employer brand: this raises questions about your genuine motivation for the role
- Ignoring the collective dimension: audit is practiced in teams, in the field, at the client's site — an overly individualistic pitch rings false
- Not researching the firm's specialization sectors (banking/insurance, industry, tech) even though this information is public

Sample answer
"I discovered audit during an M1 internship in management control, where I worked alongside external auditors during year-end close. I was struck by the diversity of their engagements — moving from an industrial file to a banking file within weeks — and by the rigor of their methodology. That versatility and accelerated training are exactly what I'm looking for early in my career. In the medium term, I want to build sector expertise before moving into corporate finance or transaction services."
This structure works because it relies on a verifiable fact, explains clear reasoning, and projects a realistic trajectory without locking in your entire future.
