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.

After the interview round, I was invited to a pair programming interview. This interview was about developing a mechanism through a interface given by the interviewers to update the exchange date and reduce costs to the company. Then I was invited to the next round of a technical interview for a "system design interview". This term is broad and there was no clear instruction to which area I should be preparing for. At the end, it was more like another pair programming interview which the questions are revolving around the question "Can you design an elevator?".
