The process included a take-home React assignment, three technical rounds covering algorithmic optimization, React architecture, core JavaScript internals (event loop, closures, async/await), and a two-hour machine coding challenge to build a restaurant listing feed with infinite scroll and filtering. The candidate was rejected after Round 3 due to gaps in error boundary handling and API fallback states. Key takeaways: master virtualized lists, graceful degradation, and vanilla async patterns like debouncing and race condition handling. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What kind of machine coding task should I expect in a frontend SDE-2 interview at a company like Swiggy? Expect a live, timed build of a scaled product feature such as a restaurant listing feed with multi-layered filtering by pricing, category, and rating, optimized search, and a high-performance infinite scroll mechanism. The round can run around two hours, and evaluators focus heavily on UI fluidity during fast scrolling and on error-boundary handling and API fallback states. _Candidates prepping for machine coding rounds can find similar interview breakdowns and frontend architecture discussions on daily.dev._ ### What topics come up in a core JavaScript deep-dive interview round for a senior frontend role? Expect in-depth questions on the event loop, microtask versus macrotask execution order, closures, lexical scoping, explicit this binding, and the underlying engine mechanics of async/await. Interviewers may also ask about common browser memory leak patterns and require debugging broken asynchronous state transitions in an existing code snippet. _daily.dev surfaces deep dives on JavaScript internals for engineers studying event loop and async behavior._ ### What should I focus on to pass a high-scale frontend interview bar involving infinite scroll? Understand virtualized lists, windowing, and DOM recycling to keep the UI lag-free while rendering large datasets, since simply making infinite scroll work is not enough. Interviewers at companies with high-scale product feeds also expect strong handling of race conditions, debounced search inputs, and graceful degradation when APIs fail or time out. _Engineers refining infinite scroll and virtualization skills can track related frontend performance content on daily.dev._ ## Similar posts on daily.dev - [Inside the Wayfair Frontend SDE-2 Interview: A Complete Breakdown](https://daily.dev/posts/inside-the-wayfair-frontend-sde-2-interview-a-complete-breakdown-bbbyicnlv) · Medium · 0 upvotes · 0 comments - [My Interview Experience for a Senior Frontend Engineer Role at Razorpay](https://daily.dev/posts/my-interview-experience-for-a-senior-frontend-engineer-role-at-razorpay-snvjlurvs) · Medium · 6 upvotes · 0 comments - [District \(Zomato\) SDE-1 Interview Experience \(Off-Campus, 56 LPA CTC\)](https://daily.dev/posts/district-zomato-sde-1-interview-experience-off-campus-56-lpa-ctc--icujmwe8t) · Medium · 0 upvotes · 0 comments --- Tags: [#javascript](https://daily.dev/tags/javascript), [#react](https://daily.dev/tags/react), [#performance](https://daily.dev/tags/performance), [#frontend](https://daily.dev/tags/frontend), [#interview-questions](https://daily.dev/tags/interview-questions) [View this post on daily.dev](https://daily.dev/posts/deconstructing-the-swiggy-frontend-sde-2-interview-loop-48mke0uuw) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Deconstructing the Swiggy Frontend SDE-2 Interview Loop","url":"https://daily.dev/posts/deconstructing-the-swiggy-frontend-sde-2-interview-loop-48mke0uuw","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/deconstructing-the-swiggy-frontend-sde-2-interview-loop-48mke0uuw"},"datePublished":"2026-07-23T10:08:02.905Z","dateModified":"2026-09-14T06:49:57.678Z","description":"A breakdown of the Swiggy SDE-2 Frontend interview loop, based on a colleague's firsthand experience.
