The technical interview began with a basic introduction, followed by several JavaScript-related questions. I was asked about core concepts such as map, filter, reduce, sort, promises, and async/await. They also tested my understanding of React, including topics like reconciliation, component creation, the virtual DOM, and template literals. Additionally, I was asked how to set up a Node.js project and create API endpoints. The interviewer went into detail while discussing my projects, asking about the technologies used and my specific contributions.
