They asked me a mix of interesting LeetCode easy problems and questions about Node.js and React.js. In Node.js, they focused on event loops, threads, async/await, promises, and callback functions. For React.js, they delved into virtual DOM, dependency arrays, React hooks, components, and general concepts such as sessions, cookies, caches. They also threw in questions about SQL and NoSQL databases, covering topics like TTL (Time to Live), and touched on a bit of data structure and algorithms, including trees, hashmaps, and time complexities. It was a good blend of coding problems and understanding how I handle different aspects of web development.
