Two rounds of Face to Face. Both rounds were technical, focusing mainly on core Java concepts. There were also a few questions related to my profile, specifically cloud applications. The interviewer was expecting definitions rather than practical knowledge.

Basic Core Java Questions

1. What is an abstract class and interface? What is the abstraction percentage of both?

2. Multithreading: Synchronized application for amount withdrawal/deposit.

3. Where is synchronized applied?

4. Difference between service-based and product-based applications.

5. Sample output for static blocks and instance initializer blocks.
