The interview started with a discussion of my project. The interviewer asked me to explain the code, including technologies used, project structure, and flow of data. I gave a walkthrough of my React-based project and backend implementation. Next, I was asked to write a React code snippet to implement a specific functionality (like a button click, form handling, or dynamic rendering). Then came technical questions on core concepts: OOPs: Explained the four pillars – Inheritance, Encapsulation, Abstraction, and Polymorphism. Priority Queue: Explained its use and internal working (heap). Second Maximum Element in Array: Asked to write logic/code. MySQL: Find third highest salary using LIMIT and DISTINCT. Difference between Primary Key and Unique Key. Sorting Algorithm: Asked to explain and write Bubble Sort logic.
