Evaluation

What Deloitte interviewers evaluate

Client-centricity

Deloitte serves thousands of clients across industries. Show you understand what good client service looks like and can build relationships.

Collaboration

Deloitte's culture is team-based across all service lines. Discovery Day specifically tests how you work with others.

Commercial awareness

Know current business issues affecting Deloitte's clients — ESG, digital transformation, regulatory changes.

Professional scepticism

For audit roles especially — they want people who question assumptions and think critically.

Adaptability

Service lines are broad. Projects vary hugely. Show you can handle variety and ambiguity.

Values alignment

Deloitte heavily screens for values fit. Know their five values and weave them into your answers naturally.

Avoid

Common mistakes at Deloitte assessment centres

Trying to dominate the group exercise. Deloitte explicitly rewards collaboration. Build on others' points and summarise for the group.

Not knowing Deloitte's values. They assess against their values framework — know them and demonstrate them naturally.

Being too generic in the partner interview. Reference specific service lines, recent work, or firm initiatives.

Ignoring other candidates. The social elements (lunch, breaks) are part of the assessment. Be friendly and engaged throughout.

Under-preparing for the case study or written exercise. Practise structuring analysis under time pressure.

Not having questions prepared. "No questions" signals lack of genuine interest.
