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.

Real interview reports from people who went through the Zs Associates process.
The process was pretty straightforward and felt very consulting-style. I had two interviews back to back, and both were split between behavioral and case study sections. The behavioral part was standard enough, with the usual questions about my background and where I see myself in the future. The case portion was more about how I think than about memorizing anything technical. They put data in front of me and asked me to talk through it, explain what I was seeing, and make a recommendation based on the goal they wanted to achieve.
What stood out most was how chart-heavy the case was. I had to read through a lot of charts and graphs, and one of the more memorable prompts was around electric vehicles: given the information provided, which city should add EV chargers and what sites in that city would make the most sense. The interviewer wasn’t trying to trip me up, but they did want clear reasoning and a structured answer. The timing was reasonable, and the questions were well phrased, though I did have some internet issues during the interview, which was annoying. Overall it felt very manageable if you prepare for case interviews and come ready to ask thoughtful questions back. I ended up getting the offer, and my main takeaway was that they care a lot about how you interpret data and communicate your recommendation, not just whether you land on the perfect answer.
Prep tip from this candidate
Practice walking through chart-heavy case prompts out loud, especially ones where you have to choose between locations or recommend an action from limited data. Also be ready for a standard behavioral question like where you see yourself in 10 years, and make sure your recommendation is structured and clearly justified.

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.
