I was interviewed over the phone due to fact I live in another country. First call explained what are their internal systems, and the issues they are facing with. I have suggested few solutions to their issues. After that coding exercise was scheduled, I had to share my screen through a Webex for that. I was given a String to reverse without using String.reverse method. I have build up a logic to reverse it and what they wanted to see is, 1. how I can decompose that logic in to several methods, so that they can use that logic for different purposes. (Reusable code) 2. Comments to explain the logic 3. How to handle exception, and which layer I should capture the exceptions.

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.
