I interviewed for the post of BTSA( Business Technology Solution Analyst) as a part of my on campus placement season. Round 1 Round 1 was online test which consisted of nearly 6-7 sections. There was verbal, critical thinking, logical reasoning, aptitude, case study etc. It was nearly 1hr. This is an elimination round Round 2 This was a communication round. There was tests related to listening, understanding, reading, writing, etc. This was also an elimination round but the number of people who got eliminated was less. Round 3 This was a technical round. There was 1 coding qn on DSA, however, there was only one option for JAVA and Python. There were 2 SQL query writing questions. 10 SQL mcqs were also there. The overall difficulty was medium After these 3 rounds, they shortlisted nearly 22 people for the BTSA role and 52 people for the DAA role. Technical Interview Round 1 I was the first one to go. Initially started with an introduction, then he moved through the resume. I had done a project on CNN, which the interviewer had good knowledge of. In-depth questions were asked on this part. Then there was so many questions from Python and various libraries involving Python. Then he moved to DSA. Questions were i. To check if a string is a palindrome, he asked for 4 approaches however I could answer 3 ii. To find the longest palindrome in a string which was easy for me Then he went for SQL queries, many tables were made and queries were told to be written. he wanted a different approach for each question. I would rate the SQL questions to be medium hard to hard. Then there was a guesstimate question based on the number of people traveling in the Delhi metro at 9:00 AM. There were also many situational reaction-type questions. Some business-building-type questions were also asked. Monty Hall problem was asked as a puzzle. The interview was almost 1 hr 15 min. I was having no hopes, However i was called for round 2.
Interview round 2 He initially started with HR related questions. Later stage he moved to some technical questions which was easy. 2 Guessestimates were given. One was to find number of planes departing from Trivandrum Airport and another one was to find volume of the chair which I was sitting in. I was able to answer everything however Interviewer was a bit arrogant. So the list came that day itself. I was not selected. ZS usually conduct diversity hiring. Only 3 people were selected for my role of which 2 of them were girls. In the overall 9 selected 7 was girls However it was a really nice interview experience :)

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.
