The two candidate reports for the ZS Associates Product Manager interview describe different formats, so prepare for both rather than expecting one fixed loop.
One candidate, who received an offer, describes a sequence of elimination gates. It began with a technical screen on SQL fundamentals, including the difference between UNION and UNION ALL and how each handles duplicate rows. A communication round followed, then a second technical assessment on SQL and product-management domain knowledge. This candidate rated the difficulty moderate to high, but said the questions tested fundamentals rather than tricks. They also said that role-specific preparation helped more than generic interview prep.
The other candidate, who was rejected, describes a single day with four interviewers. The day opened with a marketing case in which the interviewer interrupted frequently. Next was a looser, unstructured case with the hiring manager. The third interview was shortened because the interviewer arrived late. The last was a conversation with a peer in the role. The candidate was asked to walk through a past project. The recruiter later said the team liked their skills but chose someone with more years of experience.
In practice, be ready to explain SQL basics clearly, structure a marketing or open-ended case while being interrupted, and describe one past project concisely. Confirm the schedule and format with your recruiter, because the reports differ.

Real interview reports from people who went through the Zs Associates process.
I started with a technical screening that covered SQL fundamentals—they asked about the difference between UNION and UNION ALL, which tested whether I understood how these operators handle duplicate rows. That was my first elimination gate. I prepared by reviewing company-specific and role-specific concepts rather than generic interview prep, which paid off. After passing that, I moved into a communication round where they wanted to see how I could articulate my thinking and ideas clearly. Then came a second technical assessment, again on SQL and core domain knowledge relevant to the product manager role. Throughout the process, every round felt like it could be your last, so I went in knowing that each conversation needed to demonstrate both technical competence and strong communication. The interviews had moderate to high difficulty overall, but they weren't trying to trick me—they were genuinely testing whether I understood the fundamentals of my domain and could discuss them confidently. The whole experience reinforced that this company values people who've done their homework on their core skills and can explain their reasoning clearly.
Prep tip from this candidate
Focus on SQL fundamentals, especially operators like UNION vs UNION ALL, and brush up on core domain knowledge specific to product management at ZS Associates. Every round is treated as an elimination gate, so go in prepared to discuss your domain expertise with confidence.

Synthesized from candidate reports. Individual experiences may vary.
One candidate reports that the process began with a technical screen on SQL fundamentals. They were asked the difference between UNION and UNION ALL, which tests how duplicate rows are handled. The candidate treated this as the first elimination gate, so it is worth reviewing core SQL operators beforehand.
The same candidate describes a communication round in which interviewers wanted to see how clearly they could explain their thinking and ideas. Candidates may want to practice structured, concise answers about their reasoning, since this round was framed as another pass-or-fail step.
According to that candidate, a second technical assessment returned to SQL and core domain knowledge relevant to product management. They rated the overall difficulty moderate to high, but said the questions focused on fundamentals and on explaining them confidently rather than on tricks. This candidate received an offer.
Another candidate describes four interviews back to back in one day: a marketing case with frequent interruptions, an unstructured case with the hiring manager, a shortened third interview after a late start, and a peer conversation. Candidates may want to practice thinking aloud while being interrupted. This format may not apply to every candidate.
One candidate received an offer after the SQL and communication rounds. The other had to follow up with the recruiter after the expected decision date passed, and was told the team liked them but chose someone with more years of experience. Plan to follow up politely if a promised update date passes.
