ZS Associates visited our campus for a recruitment drive, providing an exciting opportunity for students to showcase their skills and secure positions in their esteemed organization. SQL query Round 1 There was an online test (Only MCQ's) having 4 sections (Verbal, Logical Reasoning , CS subject quiz and Aptitude ). Shortlisted students from this round gave a Video interview round. Round 2 This was a case study round. The case study was based on DBMS. We were asked to write the Dynamic Programming or the algorithm. Case study was tough. Time given was 35 minutes. They were not expecting the full answer, only logic part was checked. Some situation based and some guess estimates were also asked. Also, in this round interviewer gave me 3 puzzles. Measuring 6L water from 4L and 9L buckets https://www.cut-the-knot.org/blue/TenByTen.shtml https://www.geeksforgeeks.org/aptitude/puzzle-1-how-to-measure-45-minutes-using-two-identical-wires/ Around 80% of students were eliminated after this round. Round 3 In this round, my projects were discussed in detail that I mentioned in my Resume. Also, he gave me 3 more puzzles which I don't remember. Some questions on DBMS were asked which were based on joins, group by etc. Some questions like: What is Swap two numbers without using the third variable . Also, he asked me to write corner test cases Then he asked me some questions related to Team Management. Some common HR questions like Why ZS, My strengths and weakness were also asked. Finally, I was selected. Tip: Be confident. Maintain a smile throughout the interview.

About Zs Associates Interview Reports
This question was reported by a candidate who interviewed at Zs Associates. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.
Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at Zs Associates are the higher-signal extractions to take from this report.
For broader preparation context, the Zs Associates interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.
How To Practice This Type of Question
Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.
Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in Zs Associates reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Zs Associates Round
Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.
The single most predictive failure mode in Zs Associates reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
