Deloitte Business Analyst interviews vary by office and team, so the most useful preparation covers a few recurring themes rather than one fixed script. Most candidates describe an early HR conversation, sometimes reached through a headhunter, followed by one or more interviews with a manager. One candidate also took an English communication test before the virtual rounds.
The interviews lean heavily on your résumé. Candidates report being asked to talk through past projects, including what role they played and what process they followed, and whether the skills on their CV were real. Business-analysis fundamentals come up directly: requirements gathering, stakeholder communication, documentation, functional analysis, and testing activities such as SIT and UAT. Standard behavioral prompts also appear, including why Deloitte, a weakness and your most important achievement. One candidate was unexpectedly asked about OOP concepts, so a quick review is worthwhile.
Case and reasoning work shows up in several forms. One candidate had an entry-level IT case study with a manager. Another had estimation and probability questions, such as valuing a market or calculating the chance of not rolling a six with two dice. One candidate from a computer science background struggled in an hour-long whiteboard case because they had no consulting framework. Practice structuring a problem out loud and explaining your assumptions clearly.
Tool depth depends on the team. One candidate reports light SQL questions. Another completed an Excel data-consolidation exercise in which the interviewer explored alternative formulas, so be ready to solve the same task more than one way. Final conversations can also cover travel comfort and salary expectations.
