Practice Machine Coding Rounds Like a Real Interview

A machine coding round is a timed session (60–90 minutes) where you build a functional UI component or small application from scratch — for example, an autocomplete search, infinite scroll list, Kanban board, or star rating widget. The interviewer evaluates your code quality, component design, edge case handling, and how you approach the problem. It is common at Indian tech companies like Flipkart, Swiggy, Razorpay, Meesho, and CRED.

Common machine coding problems include: autocomplete/typeahead, infinite scroll, drag-and-drop list, file upload with progress, multi-select dropdown, modal/dialog, accordion/tabs, image carousel, star rating, kanban board, nested comments, pagination component, and real-time search filter. Companies like Flipkart focus on building scalable, reusable components with clean state management.

To prepare for machine coding rounds: (1) Practice building UI components from scratch without referencing docs; (2) Focus on clean state management, prop design, and edge cases; (3) Time yourself — aim to have a working solution in 45–60 minutes; (4) Practice with live preview so you can see your component rendering; (5) Study company-specific problem types — Flipkart focuses on e-commerce UIs, Swiggy on real-time updates, Razorpay on form flows.

Machine coding rounds are extremely common in Indian tech company interviews. Companies that conduct machine coding rounds include Flipkart, Swiggy, Razorpay, CRED, Meesho, Zepto, Groww, PhonePe, Juspay, Nykaa, and many more. Some FAANG companies also conduct machine coding-style rounds as part of their frontend interview process.
