The interviewers were really good and made me comfortable during the process. The major problem that followed was my primary programming language. They were leaning a little more towards C# and were expecting the same from me. The interview process involved a technical screen and then an onsite round. Overall, the interviewers were friendly and created a comfortable environment, but there was a challenge regarding my primary programming language, as they seemed to favor C#.

Technical Coding
It was a 3 round interview process. All rounds consisted of theoretical questions about product architecture. The first round was a really good discussion, the interviewer was attentive to my explanations. In the second round, the interviewer seemed to be in a rush. They asked about the class name used for business logic, and I'm not sure if they were checking naming conventions. For SQL queries, they wanted the exact query they had in mind, and even though mine was correct, they said it was wrong. They questioned the architecture of my current company's product without fully listening. It was generally an easy interview, but it really depends on the interviewer if you get selected.

The process was smooth, with 2 rounds total. One round lasted over an hour, covering Java, React, and Spring Boot. The main focus was hands-on practice, so I did all the questions while sharing my screen. The coding question was simple and only on streams. The second round also focused on React, Spring Boot, and Java, discussing project challenges and some questions.
