UiPath Software Engineer interview experience

HR had communicated four rounds at first, but after I completed the fourth, they added a fifth and told me it wasn’t a rejection step—just one more. I was ultimately rejected after finishing all five.

Round one was technical and covered several areas: explaining an event loop, working with TypeScript utility types, and a UI task where I had to fetch data every 500 milliseconds and render 10,000 rows with searching and filtering. Round two was system design for a Notification Center, including multiple data sources, read/unread state, filtering, state management, and a component hierarchy.
