Type · data-structures
You have a stream of real-time location updates for delivery partners. Design a data structure to efficiently find all delivery partners within a given radius of a specific point (e.g., a customer's location).
How to Pass the Zepto Software Engineer Interview in 2026
The Zepto DNA (TL;DR)
Zepto's 'Fastest Online Grocery Delivery' mission drives the interview focus on rapid execution and operational rigor. Interviewers assess how candidates apply structured thinking to deliver tangible results quickly, often probing for examples of navigating ambiguity and achieving speed-to-market.
The Zepto Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 2
Round 2
Coding ScreenLeetCode-medium algorithmic problems under time pressure. - 3
Round 3
System DesignDistributed systems, trade-offs at scale, architecture under constraints. - 4
Round 4
Onsite CodingLeetCode-hard, debugging, code clarity, edge cases. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of Zepto interview outcomes, avoid these common traps:
- Not being able to articulate their own reasoning clearly.
- Not considering edge cases like impossible delivery times or overlapping routes.
- Using a naive approach like iterating through all partners for each query.
- Not considering all layers of the system (frontend, backend, external services, data).

2
Coding Screen
3- 2
Type · algorithmic
Given a list of delivery orders, each with a pickup location, drop-off location, and a requested delivery time, design an algorithm to assign orders to delivery partners to minimize lateness. Assume delivery partners can only handle one order at a time and travel time between locations is known. - 3

System Design
3- 4
Type · architecture
Design a system to manage Zepto's fleet of delivery partners. Consider aspects like real-time tracking, dynamic dispatching, partner availability, and performance monitoring. - 5
Type · scalability
Zepto is experiencing rapid growth. How would you design the order processing pipeline to handle a 10x increase in order volume while maintaining low latency for customers? - + 1 more questions in this round (sign up to unlock)
4
Onsite Coding
4- 6
Type · hard-algorithmic
Design an algorithm to find the optimal batching of pickup and drop-off tasks for a single delivery partner to minimize total travel time, given a set of pending orders and their locations. This is a variation of the Traveling Salesperson Problem (TSP) or Vehicle Routing Problem (VRP). - 7
Type · debugging
A customer reports that their order arrived significantly later than the initially estimated time, and the app showed an incorrect ETA throughout. Analyze the potential causes in the system and outline how you would debug this issue. - + 2 more questions in this round (sign up to unlock)

Type · ownership
Tell me about a time you encountered a critical bug in production that was impacting users. What was your role in identifying, debugging, and resolving the issue, and what did you learn from the experience? - 9
