Company interview guide
Questions built for your practice at Deloitte, each with a guide to structuring the answer against your own experience.
The final round is reported to include a group case with five distinct, timed stages: assigned into a group of three to six, ten minutes to read the case alone, twenty minutes of group discussion while interviewers watch, then twenty minutes of individual questioning.
That structure sits alongside a separate thirty to forty five minute one on one case and a thirty to forty five minute behavioural interview in the same final round, reported to be run by more senior staff with a heavier weight on cultural fit and coachability than the first round screener.Reported questions

02 / Hiring process
5 stages from application to offer. Application and psychometric assessment is reported to be the one that decides it.
5stages
An online application paired with a psychometric assessment, reported to run before a recruiter is involved for most practices.
A screening conversation confirming background and basic fit ahead of the case rounds.
Reported to be primarily a screener: interviewers check that you can actually work through a case and show the potential to do this as real work, with the case itself more structured and numbers heavy than the final round's.
Reported to run three parts with more senior interviewers: a thirty to forty five minute behavioural interview, a thirty to forty five minute one on one case, and a group case where a group of three to six candidates gets ten minutes to read the case alone, twenty minutes to discuss it while interviewers observe, then twenty minutes of individual questioning.
A shorter, more conversational round with a partner focused on career fit, reported to still factor into the final decision rather than being a formality after everything else is settled.
Ask before the interview: what will this round cover, who will I meet, and is there anything I should prepare?The question almost nobody asks
03 / Question library
The assessment, the case rounds and the four values apply across every practice, so the core set below covers that ground. Each practice then adds the technical depth specific to it.

05 / The four values
Deloitte publishes four shared values in this exact language. Bring one real story for each rather than a general answer about wanting to work at a Big Four firm.
4stories
A time you protected someone's trust in you even when a smaller, easier version of the truth was available.
A time you delivered a result a client or stakeholder didn't expect, not just what was asked for.
A time you looked out for a colleague's development or wellbeing, not just the task in front of you both.
A time a genuinely different perspective changed a real decision, not just made a meeting feel more inclusive.
06 / Before you apply
The part of the process that eliminates most people is not the interview. It is what happens around it, and almost none of it is written down anywhere.
It is reported to be scored across three distinct, timed phases on its own, on top of the individual case and the behavioural round in the same final day. Treating it as informal because it's a group activity is a common and costly misread.
The first is reported to be a more structured, quantitative screener checking baseline capability. The final round is reported to weigh cultural fit and coachability more heavily, with more senior interviewers in the room.
Deloitte's own site splits its listings between Commercial and Government and Public Services from the first search. A candidate researching only the commercial practice can walk into a GPS interview unprepared for the clearance and compliance realities specific to that client base.
A live sample showed the same controllership and record to report role posted separately across five different industry verticals. Candidates expecting a single generic finance interview are reported to be caught off guard by how industry specific the actual conversation gets.
