Razorpay Interview Questions
& Process

The interview process was pretty smooth and not super hard, with just two rounds. The last round was an in-person chat with the Head of TA, and it went well. They told me I was one of the best candidates they'd seen, and we got into talking about pay and when I could start. But then, after about four days of back-and-forth on the offer, they surprised me by saying they chose someone else. This was unexpected since we were already discussing specifics like salary, which made me think an offer was coming. I get that companies see lots of people, but it would have been better and more honest to say that earlier instead of starting negotiations that set expectations. Better communication throughout would really improve things for candidates.

So Razorpay came to my campus for Backend Engineer Intern positions. It was pretty tough but I learned a lot. First, we had an Online Assessment with 3 DSA questions to do in 1.5 hours, really tested how fast I can solve problems. After that, I got into the DSA interview. They gave me two problems: LeetCode 665 – Non-decreasing Array and Largest Rectangle in Histogram. I managed to solve both and explained how I did it, plus any tricky parts and how to make it better. The interviewer was super nice and made it easy to talk about it. Then, I had a Hiring Manager round. We talked about my projects and what I've actually done. Also covered CS basics like OS and networks, and my whole BTech experience, like what I learned. It was a good chat, more like a conversation, focusing on if I really understood things and how they apply in the real world.

I applied through the website. The HR chat was about my background, the tech I know (React, JS/TS), and what salary I'm looking for. First, I had an online test with two coding problems about arrays and async JS. Then, a live coding session where I had to build a small component with pagination and API search, and talk about performance, state, and how I structure code. After that, I had a system design round where I designed an analytics dashboard with filters, caching, rate limiting, and virtual scrolling. They cared about how clear I was, the trade-offs I made, and if it could scale. The last round was with the hiring manager, where we talked about projects I've owned, how I'd deal with problems in production, and how I work with others. It was a pretty chill chat.

The interview process had 4 rounds. The first round was a machine coding round where you need to submit a fully running code, making sure to use design patterns and principles correctly. The second round was High Level Design (HLD), testing your ability to design a system using different building blocks and create a scalable design. Round 3 was a Deep Dive into your previous work and a discussion about it. Finally, Round 4 was with the Hiring Manager (HM), covering behavioral questions and some HLD problems.
