Difficult Positive Pakistan

My interview experience leaned heavily into full-stack fundamentals. I talked about MERN knowledge and how I think about the backend and frontend together—especially around database work and which libraries to use for what. During the conversation, they asked questions about JavaScript functionality and then followed up with TypeScript questions. I also got questions on frontend frameworks and how I approach the logic in the browser while still keeping an eye on the server side.

The difficulty felt high from the scope of what I had to cover in one sitting. I remember feeling like it wasn’t just about naming technologies; they wanted me to connect the pieces and explain how the pieces fit together in a real system. I left with the impression that the role would require a broad, practical understanding across the stack. It didn’t lead to an offer, but the technical depth was the clearest signal of what they cared about most.
