Round 1 Statement Round We were 5 people and given a problem statement and we were asked to design application or think about how should be the application and present our Idea individually. My topic was “design parking app which will show the available parking slots and fare in a particular area”
Round 2 Technical Interview 1 1. What are ACID properties with real life examples. 2. what is Linked list and reverse the linked list using single pointer/ 2 pointers. 3. What is RDBMS. 4. what is virtual memory 5. what are primitive data types? what is bitwise operators? 6. what is primary key? unique key? 7. Can unique key be a primary key? 8. What is foreign key? can foreign key be Null? 9. what is normalization? why should we do normalization? 10. normalized form is better or storing in a single table/ 2 tables is better? 11. create database of IPL 12. write a query to find name of a player with maximum number of runs in a match on given date and given venue. 13. query 1 2 3 4 5 6 7 8 9=100 solve this by placing or without placing any operator. 14. one more puzzle of making the probability of ball selecting… etc.
Round 3 Technical Interview 2 1. OOPS concept with real life examples. 2. what is class n object. comparison with real life. 3. program to swap numbers without using temp variable. 4. abstract class, friend class, and other questions related to class concept. 5. Inheritance and types. 6. WAP to print series, with printing characters if divisible by 3, 5, 3&5. 7. Some queries and concepts of RDBMS. 8. OS concepts 9. Puzzle of no of iteration to find light weight ball out of 9 balls.

About Zopper Interview Reports
This question was reported by a candidate who interviewed at Zopper. 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 Zopper are the higher-signal extractions to take from this report.
For broader preparation context, the Zopper 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 Zopper reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Zopper 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 Zopper 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.
