The Swiggy Frontend Engineer interview process
Online assessment (90–120 min, 2–3 medium DSA + debugging on HackerRank/HackerEarth) → 2–3 technical rounds (DSA, plus machine coding and/or LLD/HLD) → managerial / team-fit round → HR. Usually 1–3 weeks end to end.
What Swiggy actually screens for
Strong DSA plus, for many roles, a machine-coding round where you build a working feature end-to-end in a fixed window, and low-/high-level design (failover, resiliency, API design, data modeling). Project deep-dives are common.
How to clear the bar: The machine-coding round rewards clean, extensible OOP and working code over cleverness. Be solid on core DSA (arrays, trees, hash maps, graphs) and able to explain time/space trade-offs out loud.

- Frontend system design
- JS / framework deep-dive
- Behavioral
Core topics to master
- JavaScript fundamentals
- React / framework internals
- Browser rendering & performance

These are representative of what comes up for this role. Practice answering them out loud — being right on paper isn't the same as explaining your reasoning under time pressure.
- Implement a debounce function and explain when you'd use throttle instead.
- Design the frontend architecture for an infinite-scroll feed.
- How does the browser turn HTML + CSS into pixels on screen?
- Tell me about a performance problem you found and fixed on the client.
