Candidates who describe ZS Associates Business Analyst-track interviews mostly point to the case study as the deciding stage. Several report online aptitude and communication assessments first, then a timed case test, then interviews that circle back to how they reached their answers. One Business Analyst candidate describes a 60-minute test of 8 to 10 data-interpretation questions that required submitting rough work as a PDF, followed by a discussion round covering that work, resume projects, SQL and guesstimates. Another describes building a market-entry presentation deck from a data-heavy case.
Guesstimates and puzzles appear in many accounts, including tyre sales in Delhi, smartphone ownership in India and a two-weighing ball puzzle. Candidates say interviewers cared more about assumptions and structure than the final number. SQL comes up on analyst and technology-leaning tracks, with candidates mentioning window functions, ranking and second-highest-salary queries. A Decision Analytics candidate describes only a light Python and projects check. Behavioral questions cover team conflict, managing an underperforming team, working with global teams and why ZS. A Business Technology Solutions candidate also reports a project presentation and an airline revenue-analytics case that required specifying data tables and metrics.
Outcomes are mixed, with offers and rejections across the reports, and a few candidates mention rushed or slow scheduling. Spend most of your preparation time on timed data-interpretation cases and on explaining your calculations aloud. Keep resume projects ready to defend in detail.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report an online aptitude test covering quantitative, logical and verbal reasoning, sometimes with attention-to-detail and guesstimate sections. Some also describe a communication test with a short spoken monologue, listening questions and a written essay. Technology-leaning tracks may add SQL or coding questions.
One Business Analyst candidate describes a 60-minute test of 8 to 10 data-interpretation questions, with a few numeric answers and the rest descriptive. Rough work had to be submitted as a PDF. Other candidates mention uploading calculations or a late-night case window, so timing and format may vary.
Candidates typically report an interview that walks back through the case, asking how they reached their answers and why. Reports also mention resume and project questions, SQL basics, guesstimates and logical puzzles in the same round. Some describe building a presentation deck from a data-heavy market-entry case.
Several candidates report an extended behavioral or technical interview mixing two guesstimates, puzzles and resume questions. Examples include tyres sold in a city and smartphone ownership. SQL window functions, ranking queries and DBMS or OOP fundamentals come up on some tracks. Reports say interviewers value structure and assumptions over exact numbers.
Final conversations are reported as behavioral or fit-focused, with questions such as tell me about yourself, why ZS, handling conflict, managing teams and working across regions. Some candidates describe a manager or partner-level discussion, and one reports salary discussion at this stage. Whether this stage occurs may depend on the track.
