The interview process consisted of four rounds: one aptitude online round, two technical rounds, and one HR onsite round. The overall process was smooth.

In the first technical round, questions covered Java build factory, string builder, design patterns, and data structures. The second technical round focused on resume-based and situational questions. Finally, the HR round included general questions such as "Why do you want to switch?" and an analysis of the candidate's profile to identify a suitable position.

The only drawback is the significant amount of time taken to release the offer letter, and the HR department's delayed responses.
