Interview Types at Deloitte

1. Competency-Based Interviews

Standard across all Deloitte practices. Questions follow the pattern:

  • “Tell me about a time you demonstrated leadership”
  • “Describe a situation where you worked in a team”
  • “Give an example of when you solved a complex problem”
  • “Tell me about a time you showed initiative”

Use the STAR method:

  • Situation: Context and background
  • Task: Your responsibility
  • Action: What YOU specifically did
  • Result: Measurable outcomes

2. Case Interviews (Consulting Roles)

For Strategy & Operations, Human Capital, and M&A practices:

Types of cases:

  • Profitability (“Our client’s margins are declining—why?”)
  • Market entry (“Should this retailer expand to India?”)
  • M&A (“Should our client acquire this startup?”)

Framework approach:

  1. Clarify the problem
  2. Structure your approach
