Zepto Business Analyst interview questions & guide 2026

Interview questions at Zepto are designed to test your technical proficiency with data and your ability to apply that data to real business scenarios. Expect a mix of rigorous technical assessments and practical case studies.

SQL and Data Manipulation

These questions test your ability to handle large datasets, perform complex joins, and use window functions to solve real-time operational problems.

• How would you identify duplicate orders caused by a system glitch in a transactional database?
• Write a query to find the maximum salary of each department from an employee table.

Preparation for Zepto should focus on speed, accuracy, and business intuition. You are being evaluated not just on your ability to write code, but on your ability to extract meaning from that code to solve problems.

Technical Proficiency – You must be fluent in SQL, including advanced functions like window operations, subqueries, and complex joins. Interviewers will often ask you to share your screen and solve problems in real-time, so ensure your syntax is clean and your logic is sound.

Analytical Rigor – This involves the ability to spot anomalies and trends in data. You should be comfortable interpreting datasets involving transactions, users, and merchants, and be ready to explain the "why" behind the numbers you find.

Business Acumen – Understand the Zepto business model. Be prepared to discuss how supply chain, inventory, and delivery times impact profitability. You need to show that you can translate technical findings into recommendations that a business stakeholder can understand.

Problem-Solving Structure – When faced with a case study or a guesstimate, your process is more important than the final number. Clearly articulate your assumptions, define your variables, and break the problem down into logical steps before attempting a calculation.

The interview process at Zepto is generally direct but can be intense. While it varies by team and seniority, you should anticipate a series of technical rounds followed by a managerial or business-focused discussion. The process is heavily weighted toward your ability to perform under pressure, often involving live coding or analytical tasks shared on a screen.

This timeline illustrates the typical progression from initial screening to technical deep dives and final behavioral rounds. Use this to pace your preparation—the earlier rounds are heavily focused on SQL and data tools, while later rounds shift toward business strategy and cultural alignment. Note that the process can move quickly, so ensure you are ready for back-to-back scheduling.

Technical SQL Skills

This is the baseline for the role. You will be tested on your ability to write efficient, readable, and accurate queries.

Be ready to go over:

• Window Functions – Mastery of RANK, LEAD, LAG, and SUM() OVER(PARTITION BY...) is critical.
• Join Logic – Deep understanding of INNER, LEFT, and SELF joins, especially when dealing with time-series data.

As a Business Analyst, you are expected to be a self-starter who can navigate data ambiguity. You will work closely with the Operations, Engineering, and Product teams to provide insights that drive the business forward.

Your day-to-day will involve writing complex SQL queries to pull data for performance reports, building dashboards that visualize key metrics like order success rates, and conducting deep-dive analyses on system glitches or operational bottlenecks. You will be the person the business turns to when they need to understand why a certain metric has shifted or how a new feature is performing in the real world. Success in this role requires a balance of technical precision and the ability to communicate findings clearly to non-technical stakeholders.

A strong candidate for Zepto combines a solid engineering-adjacent skillset with a sharp business mind.

• Technical Skills – Advanced SQL is non-negotiable. Proficiency in Excel (including VLOOKUP and advanced functions) is often required. Knowledge of data visualization tools and basic scripting (like Python) is a significant advantage.
• Experience – Candidates typically have experience in analytical roles where they have had to manage high volumes of transactional data.
• Soft Skills – You must be capable of working in a high-pressure, fast-paced startup environment. Clear communication is essential, especially when explaining technical findings to stakeholders who need quick answers to make operational decisions.

Q: How long should I prepare for the SQL rounds? A: Dedicate at least 1–2 weeks to practicing advanced SQL queries, specifically focusing on window functions and self-joins. Practicing on platforms that feature real-world business datasets is highly recommended.

Q: What differentiates a successful candidate? A: Successful candidates don't just provide the correct query; they explain their logic, ask clarifying questions about the data, and offer business context on what the data implies for Zepto.

Q: Is the interview process mostly remote or in-person? A: Processes can vary, but expect a significant portion to be conducted via video calls where screen sharing is required for live technical tests.

Q: What is the culture like at Zepto? A: Zepto is a high-growth, fast-paced environment. They value speed, pragmatism, and data-driven decision-making. Expect a culture that moves quickly and demands high ownership.

• Master the Basics – Don't ignore fundamental SQL concepts. You will be expected to write flawless joins and aggregations without hesitation.
• Clarify Assumptions – When given a case study or a vague problem, always state your assumptions clearly before you start solving.
• Focus on Business Impact – Whenever you present a finding, always follow it up with "What does this mean for the business?"
• Prepare for Puzzles – Be ready for probability or logic puzzles that test your raw analytical ability.

The Business Analyst role at Zepto is an exceptional opportunity to influence the trajectory of a rapidly scaling company. By mastering your SQL fundamentals, sharpening your business intuition, and practicing a structured approach to case studies, you will be well-positioned to succeed in the interview process.
