Deloitte hires across consulting, technology, and analytics, and its interview leans heavily on communication, fit, and fundamentals rather than hard coding. For most roles, how you carry yourself matters as much as what you know. Here's how to prepare.
The Deloitte interview process
- Online assessment — aptitude, reasoning, sometimes a situational judgement test.
- Technical interview — fundamentals, your project, role-relevant skills.
- HR / behavioral interview — fit, communication, scenarios.
Deloitte technical questions
- Role-dependent: SQL and DBMS for data roles (our SQL guide), OOP and basics for dev roles (our OOPs guide).
- Your project — your contribution and impact.
- Basic coding for technical roles.
Deloitte HR & behavioral
- Tell me about yourself; why Deloitte; why consulting?
- A teamwork, leadership, or conflict example.
- Situational questions — how you'd handle a client or deadline scenario.
- Strengths, weaknesses, flexibility.
How to prepare
Rehearse your intro, "why consulting", and situational answers out loud. Greenroom runs spoken mock interviews with behavioral and situational questions and feedback on clarity. Pair it with our communication guide.
Frequently asked questions
What is the Deloitte interview process?
Deloitte's process typically includes an online assessment (aptitude, reasoning, sometimes a situational judgement test), a technical interview on fundamentals and your project, and an HR or behavioral interview focused on fit, communication and situational scenarios. Communication and consulting fit carry significant weight across roles.
What questions does Deloitte ask in the interview?
Deloitte asks role-dependent technical questions (SQL and DBMS for data roles, OOP and basics for dev roles, plus a project deep dive) and a strong set of HR and behavioral questions: tell me about yourself, why Deloitte, why consulting, teamwork and conflict examples, and situational client or deadline scenarios.
Does Deloitte focus on coding?
For most roles, Deloitte focuses more on communication, fit and fundamentals than on hard coding. Technical roles include role-relevant skills and basic coding, but polished communication, a clear 'why consulting' answer and structured situational responses often matter more than deep algorithmic ability.
How should I prepare for a Deloitte interview?
Practise the aptitude and situational judgement assessment, prepare role-relevant fundamentals and a clear project explanation, and rehearse your self-introduction, 'why consulting' and situational answers out loud. A voice-based mock interview that asks behavioral and situational questions and gives feedback on clarity helps you come across as client-ready.
