Swiggy Interview Prep

Swiggy’s interview process for SDE-2+ follows the Indian product company template: DSA, machine coding (90 min), system design, and HM round. The machine coding round is the biggest filter — candidates are expected to produce clean, extensible code with design patterns in 90 minutes. System design focuses on food-delivery-adjacent problems: dispatch, real-time tracking, and high-throughput event processing.

Tips for Swiggy Interviews

  1. Machine coding is make-or-break. Swiggy eliminates most candidates here. Practice writing full OOP solutions with Strategy/Observer patterns in 90 minutes. Working main() with output matters more than perfect coverage.
  2. Think about delivery logistics. Swiggy’s core is dispatch and routing — show awareness of geo-queries, rider assignment, and order state machines in system design.
  3. Expect follow-ups on real-time. “How does the customer see the rider moving?” is a guaranteed follow-up. Know WebSocket vs SSE, and how location pings flow through the system.
  4. DSA is medium difficulty. Swiggy’s coding rounds are LeetCode medium — focus on clean implementation and edge case handling over exotic algorithms.
