📌 My Juspay Interview Experience – From ~1000 Students to the Final Round (Software Engineer/ Product Engineer – 27 LPA) Hey everyone! I recently went through Juspay’s on-campus hiring process and it turned out to be one of the most exciting journeys of my college life. From the very first round to the final interview every step tested not just my technical skills but also how I think communicate and solve problems under pressure. Here's a breakdown of my experience: 🔹 Round 1 – Online Coding Challenge 90 minutes | 3 DSA problems (Graphs and Trees) - This round had three medium to hard level problems. I had to manage time well and make sure my logic was clean and efficient.

It tested my speed and how calmly I could think with the timer running. 🔹 Round 2 – Technical MCQ Round 60 minutes | 16 questions (Physics, Math, CS basics) - The questions required real thinking with a mix of logic, math puzzles, basic physics and core CS topics like DBMS, OS, CN and OOPs. It checked how strong my fundamentals were. 🔹 Round 3 – Hackathon Part A 3 hours | Tree of Space - Implement 3 functions; Lock, Unlock and Upgrade - We were given a tree based locking-unlocking problem. I had to use object-oriented design and write modular clean code. 🔹 Round 4 – Elimination Interview 1 to 2 hours | Live coding and explanation - This was a technical round where I had to solve two coding problems based on stacks and trees.

The focus was on how clearly I approached the problem. 🔹 Round 5 – Hackathon Part B (Slack Based) 7 hours | Optimization and Concurrency - The problem was shared on Slack. It involved: i) Explaining the complete approach of Part A and improving time and space complexities. ii) Making the solution thread-safe by introducing locking mechanisms. I wasn’t allowed to lock the entire tree or use any atomic variables. The interviewer was very helpful and it felt more like a learnathon. 🔹 Round 6 – Final Onsite Interview in Bangalore✈️(System + Cultural)| System Design, OS, DBMS, CN and Resume ✅Perks: Flight tickets and accommodation were provided by the company. - This round was more like a deep conversation. We discussed my projects, system design ideas and core CS topics.

They wanted to see how I think when building something from scratch and how well I understood the basics. 🌱 What I Learned? - How to break down real problems and build scalable solutions - Improved my soft skills and my confidence - Importance of writing clean modular code - Got more confident in system design and concurrency - Discovered areas to improve and felt proud of how far I have come. This experience helped me grow as an engineer and gave me more clarity about the kind of work I want to do. Grateful to the Juspay team and all the interviewers for such a thoughtful process.
