Curated Swiggy (Bundl Technologies (Swiggy)) interview questions with model answers.
Industry: Food Tech / Consumer Internet. Difficulty: Hard. Hiring for: SDE-1, SDE-2, Frontend Engineer, Data Scientist, Product Manager. Average package: ₹18-28 LPA (SDE-1), ₹35-55 LPA (SDE-2).
Selection process
- Resume screen (heavy emphasis on projects + GitHub for SDE-1)
- HackerEarth Online Assessment — 2 coding problems, ~90 min
- Technical Interview 1 — DSA + problem-solving (1 hour)
- Technical Interview 2 — LLD (low-level design) for SDE-1, HLD for SDE-2
- Hiring Manager Round — culture, communication, ownership
- Bar Raiser (case-by-case for senior roles)
Real interview questions and answers
Technical: Design a food delivery system (Swiggy/Zomato-like).
Cover: actors (customer, restaurant, delivery partner), key flows (browse → order → assign → track), DB schema (users, restaurants, menu items, orders, payments), real-time features (driver tracking via WebSocket, ETA calculation), scale considerations (sharding by city, caching menus, queuing order assignments). Discuss tradeoffs at each layer.
Technical: Explain how you'd implement a distributed rate limiter.
Token bucket algorithm with Redis. Each user/IP gets a bucket with max capacity + refill rate. On request: atomically check + decrement Redis counter (use Lua script for atomicity). If counter > 0, allow; else rate-limit. Use sliding window for higher accuracy. Consider per-region buckets to avoid cross-DC latency.
Technical: Find the kth largest element in an array.
Three approaches: (1) Sort O(n log n), return arr[n-k]. (2) Min-heap of size k — O(n log k). (3) Quickselect — average O(n), worst O(n²). For large arrays, quickselect is fastest on average. Discuss tradeoffs with the interviewer; they usually want quickselect or heap.
Technical: How would you handle 100K concurrent orders during a peak event?
Asynchronous processing — orders go to a queue (Kafka/SQS), background workers process. Auto-scale order-service horizontally. Use cache (Redis) for hot data (menu, restaurant status). Database: read replicas + write sharding by city. Circuit breakers on dependencies. Rate-limit at API gateway. Monitor + alert on queue depth.
Technical: Difference between SQL and NoSQL — when would you pick one over the other?
SQL (PostgreSQL): structured data, complex joins, ACID — good for orders, payments, user accounts. NoSQL (MongoDB, DynamoDB): flexible schema, horizontal scale, eventual consistency — good for menus (varying item attributes), search, analytics events, session data. Most production systems use both — pick per use case, not as a blanket choice.
Technical: What is database indexing and what are its tradeoffs?
Index = data structure (usually B-tree) that speeds up SELECTs by avoiding full table scans. Tradeoffs: faster reads, slower writes (index also updated on INSERT/UPDATE/DELETE), additional storage. Index high-cardinality columns used in WHERE/JOIN/ORDER BY. Don't over-index — each one slows writes.
Behavioral: Tell me about a time you owned an outcome end-to-end.
Swiggy values ownership heavily. Pick something where you saw a problem, drove the fix, and tracked the outcome — not just "I was assigned X." Structure: noticed gap → proposed solution → got buy-in → implemented → measured impact. Numbers matter; "cut latency 40%" beats "improved performance."
Behavioral: How do you handle disagreement with a senior engineer?
Avoid "I always defer" and "I always argue my point." Best: "I separate the technical issue from the seniority dynamic. I present my reasoning with evidence, listen to their reasoning, and if we still disagree we make a small reversible bet to test it. If they're still firm and it's their call, I commit to executing well."
Preparation tips
- Swiggy interviews lean heavy on system design and ownership — even SDE-1 gets at least one design question.
- Practice 2-3 design problems specific to Swiggy's domain: food delivery system, real-time tracking, surge pricing, restaurant search.
- Read Swiggy's engineering blog (bytes.swiggy.com) before interviewing. Reference an article in the HM round — it lands.
- For SDE-1: be very strong on DSA. Quickselect, sliding window, BFS/DFS, heap problems come up regularly.
- For frontend roles: React performance, virtual DOM, accessibility, code-splitting, real-world state management — they go deep.
Common questions about Swiggy interviews
What is the typical Swiggy SDE-1 package in 2026?
SDE-1 fresher / 0-2 YoE typically gets ₹18-28 LPA fixed + ESOPs + joining bonus. Total CTC range ₹22-35 LPA depending on negotiation, prior offers, and location (Bangalore HQ pays slightly higher).
Does Swiggy hire from tier-2/3 colleges?
Yes — Swiggy hires based on the assessment + interviews, not college brand. Tier-2/3 candidates need to clear the OA (which is the gatekeeper) and then perform in the technical rounds. Strong GitHub + open-source contributions help significantly.
How long is Swiggy's interview process?
OA to offer typically 3-4 weeks. Process: HackerEarth OA → 2 technical rounds → HM round → bar raiser (if applicable). Recruiter feedback is usually fast (3-5 days between rounds). Slowdown happens at offer-negotiation stage.
What's the work culture at Swiggy engineering?
Hybrid (3 days office in Bangalore HQ). High autonomy, strong ownership culture. Heavy on documentation and async communication. Engineering blog and open-source contributions are encouraged. Performance reviews are calibrated; promotions based on impact, not tenure.
