My Razorpay Interview Experience [November 2024]: A Deep Dive into Frontend Engineering

Overview

Razorpay is one of India's leading fintech companies, processing billions of dollars in payments annually and serving hundreds of thousands of businesses. As a product-focused organisation, Razorpay hires Senior Frontend Engineers who can architect performant, user-facing systems at scale. In November 2024, a candidate interviewing for this role shared a detailed walkthrough of the process, offering useful signals for engineers preparing for similar senior-level frontend interviews.

Interview Process

The selection process for the Senior Frontend Engineer position consisted of two technical rounds, each designed to evaluate a different dimension of the candidate's skill set:

• Round 1 — Technical Deep Dive: A conversational round assessing technical depth, decision-making, and problem-solving approach.
• Round 2 — Machine Coding Challenge: A hands-on coding round testing the candidate's ability to design and implement a feature from scratch under time constraints.

The structure reflects a common pattern in senior frontend hiring: one round to evaluate thinking and experience, and one to validate raw implementation skills.

Technical Rounds

Round 1: Technical Deep Dive

The opening round centred on the candidate's existing projects, responsibilities, and notable achievements. The interviewer placed particular emphasis on side projects and open-source contributions, viewing these as strong indicators of genuine passion for frontend engineering beyond day-to-day work.

Several core areas were explored:

• Project Walkthrough: The candidate was asked to describe complex problems previously solved and the reasoning behind key technical decisions, including trade-offs considered along the way.
• System Design: A whiteboard-style discussion examined the candidate's approach to architectural challenges. This tested the ability to reason about component composition, state management, data flow, and scalability — all critical concerns for a product operating at Razorpay's scale.
• Web Performance Optimization: Topics in this area explored how the candidate approaches performance bottlenecks in real-world applications. Performance is a recurring theme in Razorpay's product experience, given the sensitivity of payment flows where latency directly impacts conversion.

Round 2: Machine Coding Challenge

The second round required the candidate to build a working feature end-to-end within a constrained timeframe. Machine coding rounds of this style typically assess component design, state handling, edge case coverage, code structure, and the ability to ship a polished UI. Details of the specific problem statement are gated behind the original publication's paywall, but the format is well-known across Indian tech interviews and prioritises execution speed and code quality over algorithmic complexity.
