I applied through college or university. I interviewed at Optum in Jul 2019
Interview
Optum came to my campus. The first round was online coding round(2 questions) with some(30) aptitude questions. I only attempted for the 2 coding questions. Since time was very less.
I was called for the 2nd round. The interviewer was a stupid morons. Doesn't deserve to be called Software Developer. He asked me about my intro. Asked about new technologies and the tool used for version control(git). And asked me to write any code I know. I wrote the Validate BST. I cleared all the coding exams like Amazon,Cisco after attending their interview it feels like this company have bunch of useless stupid folks. Who doesn't even know what to ask. Finally i got rejected and still wondering why i got rejected 😂

I applied through a staffing agency. I interviewed at Optum
Interview
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.
