New York, NYPosted Nov 2025 · Candidate report, summarized by Dataford

I started with an online assessment that was full-stack and based around a coding problem.

After that, I went through a React-focused virtual interview centered on core React and TypeScript topics.

During that virtual stage, I was tested on component architecture and state management, and I had to build a complete UI component live as part of the process. The difficulty felt average overall, but it was clearly technical and practical.

I didn’t receive an offer. The reflection I had was that the hardest parts weren’t just knowing the concepts—they were integrating them while building the UI in real time.
