Zepto India in 2026

Zepto is India's fastest-growing quick commerce startup — founded in 2021 by Aadit Palicha and Kaivalya Vohra (both IIT Bombay dropouts), it reached a $5+ billion valuation in just 3 years. Zepto operates 10-minute grocery delivery from dark stores (micro-warehouses) across India's top cities.

In 2026, Zepto is at a critical pre-IPO stage, actively scaling engineering and is one of the most actively hiring tech companies in India. Working at Zepto means solving genuinely hard real-time logistics, inventory, and scaling problems.

Why engineers choose Zepto: Pre-IPO ESOPs with strong upside potential, high-velocity engineering culture, ownership of large systems early in career, competitive compensation, and the prestige of building at a high-growth Indian unicorn. Zepto HQ is in Mumbai with a large tech hub in Bangalore.

Interview Process

Round 1

Online Coding Assessment

90 min. 2 DSA problems on HackerRank. LeetCode Medium bar. Array/HashMap/Sliding Window/Graph problems. Must solve both to advance. Zepto moves quickly — OA result within 2–3 days.

Round 2

Technical Round 1

60 min. 1 coding problem (Medium-Hard) + backend fundamentals: REST API design, SQL/NoSQL trade-offs, basic caching (Redis), and your previous project. Focus on practical engineering judgment.

Round 3

System Design / Senior Tech

60 min. For SDE-2+: system design for a quick commerce use case. For SDE-1: this may be skipped or replaced with more coding. Zepto loves candidates who've thought about real-time systems, geospatial queries, and inventory management.

Round 4

Hiring Manager + Culture Fit

30–45 min. Behavioral: "Why Zepto?", high-stakes ownership stories, failure/learning stories. Zepto is a high-urgency startup — they filter for people who can execute fast under ambiguity. Your passion for the space matters here.

DSA for Zepto

Zepto's coding bar is similar to Swiggy, Zomato, and Dunzo — LeetCode Medium, occasionally Medium-Hard. The focus is on practical problem-solving speed, not grinding LeetCode Hard.

TopicZepto FrequencyExample Problems
Arrays & Sliding WindowVery HighMax subarray, Minimum Window Substring, Longest Substring Without Repeating Characters
HashMap & Frequency CountingVery HighTwo Sum, Group Anagrams, Top K Frequent Elements, Subarray Sum Equals K
BFS / Shortest PathHighShortest Path in Grid (relevant for delivery routing), Word Ladder, Rotten Oranges
Sorting & GreedyHighMeeting Rooms II, Interval scheduling, Task Scheduler
Trees & RecursionMediumLevel Order Traversal, LCA, Path Sum
Dynamic ProgrammingMediumCoin Change, Knapsack (relevant for pack/dispatch optimization)

System Design for Quick Commerce

Zepto's system design focuses on the unique challenges of 10-minute delivery. Here are the most common design questions and what to cover:

Design Zepto's Real-Time Order Management System
Key topics: Order lifecycle (placed → picking → packed → dispatched → delivered), event-driven architecture (Kafka for state transitions), real-time rider assignment (matching algorithm), ETA calculation, idempotency for payment + order creation, Redis for order status cache.
Design a Dark Store Inventory Management System
Key topics: Real-time inventory tracking per SKU per dark store, concurrent decrement (optimistic locking), reorder triggers, demand forecasting (ML pipeline), expiry tracking, multi-warehouse stock transfer.
Design a Rider Location Tracking & Assignment System
Key topics: Real-time GPS updates (WebSocket or polling), geospatial indexing (GeoHash, Redis GEO commands), rider assignment algorithm (nearest + availability), ETA calculation using road network (OSRM, Google Maps API), surge pricing triggers.
Design a Product Search & Catalog System for Grocery
Key topics: Elasticsearch for full-text search (ingredient, brand, category), product deduplication across 700+ dark stores, real-time availability filter per dark store, search ranking (relevance + purchase history + availability), category/filter facets.
💡
Zepto system design tip: Latency is king in quick commerce. Design for sub-100ms API responses. Show you understand: Redis for hot data (inventory, rider locations), Kafka for event streaming (order lifecycle), DynamoDB/Cassandra for high-write data, and Elasticsearch for search. If you mention GeoHash for proximity queries, you'll stand out.

Zepto Salary & ESOPs 2026

LevelExperienceBase + Bonus (LPA)ESOP Grant (4yr vest)
SDE-10–2 years₹18–30 LPA₹10–20L face value (pre-IPO)
SDE-22–5 years₹30–55 LPA₹25–60L face value

⚠️
ESOPs at pre-IPO companies: Zepto's ESOPs are issued at a strike price based on the company's current valuation. They only have monetary value at IPO or acquisition (liquidity event). Factor this in — ESOPs add potential upside but are not guaranteed. Read our complete ESOP guide for Indian engineers before negotiating.

Zepto Engineering Culture

Zepto has a distinctly different culture from established tech companies — it's fast, intense, and mission-driven. Know these before the interview:

  • Speed above all: Engineers ship weekly. The cycle from idea to production is days, not months. Be ready to move fast and be comfortable with some ambiguity.
  • Ownership culture: Small teams own large systems end-to-end — frontend, backend, data, infra. Expect to wear multiple hats, especially at SDE-1/2 levels.
  • Data-driven: Every decision is backed by metrics. Engineers write SQL dashboards, own their service's SLOs, and are expected to understand the business impact of their work.
  • Founder proximity: Zepto's founders are deeply technical and involved in engineering decisions. The interview pipeline often includes interaction with or awareness of founder values.
  • Work intensity: This is a startup. Engineers regularly work 50–60 hours/week, with spikes during major launches (new cities, new verticals). The compensation reflects this.

Frequently Asked Questions

What tech stack does Zepto use?
Zepto's primary backend is Java (Spring Boot) and Python for data pipelines. Frontend: React Native (mobile), React (web). Databases: PostgreSQL (transactional), Redis (caching, pub-sub), Elasticsearch (search), Kafka (event streaming). Infrastructure: AWS (primarily). The stack is similar to Swiggy and Dunzo — modern, microservices-based.
Does Zepto hire freshers from campus?
Zepto does limited campus hiring from IITs, NITs, and BITS Pilani. Most hiring is experienced (2+ years). For freshers targeting Zepto, the path is: strong CGPA + internship experience + excellent DSA → apply via Zepto's careers page or referral. Zepto also regularly sponsors hackathons and coding competitions where they scout talent.
Where is Zepto's tech office in India?
Zepto's engineering is split between Mumbai (HQ — Bandra) and Bangalore (engineering hub). Most senior tech roles and backend engineering are based in Bangalore. The Mumbai office houses founders, product, and business teams. Zepto is generally open to Bangalore-only arrangements for tech roles.
