A total of 3 rounds were conducted at our college. CoCubes Aptitude + Coding Test Technical Round HR Round The Aptitude multiple-choice questions were quite difficult (CAT Level) and coding questions were easy. You need to score maximum score in both sections.

My interview process started with a 30-minute recruiter call where we discussed my current work at Optum, my stack, and what I was looking for in the next role. A few days later I had a technical phone screen with one of the senior engineers on the team. We spent about 45 minutes on a coding problem around string manipulation and then walked through a few questions on Java concurrency and Spring Boot internals. After that I moved to the virtual onsite, which was four rounds spread across a single day. The first round was a system design discussion where I designed a scalable order management service using event-driven patterns with Kafka. The second was a deep dive into React and Next.js, covering rendering strategies, state management, and how I would structure a large frontend codebase. The third was a hands-on coding round on a shared editor where I built out a small API with proper validation and error handling. The final round was behavioral, focused on cross-team collaboration, conflict resolution, and how I approach mentoring. I got feedback within a week, followed by a hiring manager wrap-up and an offer conversation shortly after.
