Big 4 Interview Prep: Structured Answering

Big 4 interviewers are screening for structure, judgment, and communication under pressure. If your answer is clear in the first 20 seconds, your odds improve fast.

Use the PREP structure

• Point: answer the question directly
• Reason: explain why this is the right call
• Evidence: add one concrete data point or example
• Point: restate with business impact

Mini example

Question: "How would you improve sales for a soft drink brand?"

• Point: focus on distribution in high-frequency channels first
• Reason: awareness is wasted if product availability is weak
• Evidence: top-performing brands win by being easy to find at decision moments
• Point: fix availability first, then scale marketing

What to avoid

• giving context before answering the question
• listing multiple ideas with no prioritization
• using buzzwords without measurable impact

Elite edge for consulting and banking applicants

• prepare one 30-second and one 90-second version of each answer
• attach one metric to every recommendation
• close every answer with implementation feasibility
