Technical Coding
I applied via naukri and got a call from HR. I mentioned my internship experience. The first round was coding and I passed. They called me for a second round on another day. Upon arrival, they changed the requirement completely, looking for candidates with industrial experience. They also called me after the first round and gave me a call letter. It's disappointing that they didn't mention the need for experience earlier. I feel like I wasted my money, time, and energy. Worst management. Some people also received calls saying it was a walk-in. HCL HR might assume everyone has free time. Worst company.

Technical Behavioral
The interview process was good and ran smoothly. It started with a 1-hour first round covering basic Java 8, Spring Boot, and AWS. Following that was a second round, about 30 minutes long, focusing more on project management and the technology stacks I've used. Finally, there was an HR round where they seemed keen on reducing the offered salary, making compensation a significant point of discussion.

Technical Behavioral
I went through 2 interview rounds. The first was technical, focusing on core Java, multithreading, Spring, and Hibernate. They asked about the difference between HashMap and HashSet, thread pools, SQL statements, Spring MVC, and web services like SOAP and REST. The second round was with the manager, where we discussed my past projects and some behavioral questions. The overall interview felt easy.
