Easy questions, like OOP concepts and how to implement them in Java, to more complex questions, like multithreading in Java. I also had to solve one problem, similar to medium-level LeetCode problems.

I had a 30-minute interview, in which I was asked basic questions about Java and OOP programming. They were more interested in my knowledge and in what projects I was involved in.

I received a call from HR. The interview was scheduled for two days later. It was a good experience. First, they asked about my work experience. Then, they asked questions related to Java OOPs, collections, the Spring Framework, and databases.
