Technical Round 3 : This round focused on Low-Level Design (LLD). I was asked to design an OTP-based notification system. The interviewer explored various aspects of the system, including design patterns, class structure, and the methods I would implement. Once he was satisfied with my overall approach and design, he asked me to write the code for it.

I successfully created the interface, service class, and the necessary method implementations. Following that, the interviewer posed several scenario-based questions and asked how I would adapt my design using appropriate design patterns

Technical Round 4: This round was conducted by the Hiring Manager and was centered around my current project. The interviewer delved deeply into every component of the project, questioning my technical choices and understanding of the architecture. He was particularly interested in the design decisions and the rationale behind selecting specific technologies.

Later, he presented a few scenario-based questions, which I answered using the STAR (Situation, Task, Action, Result) approach, ensuring clarity and structure in my responses.

After a week, received a call from recruiter regarding selection and further steps. Received offer by next week.

All the interviewers and HR were very helpful and nice throughout the process.
