The interview process included an initial coding test, followed by two rounds of in-depth technical interviews. The first technical round was conducted by a technical lead from the development team, and the second was with the Engineering Manager. Just so you know, the interview difficulty at Sirion for this role is quite high, so make sure you're well-prepared.

The interview process consisted of 1 written test and 3 in-person technical interviews. Initially, the recruitment agency communicated that the decision would be made after 1 written and 2 technical interviews. However, a total of 1 written and 3 technical interviews were conducted. I believe I answered most of the questions well. The interviewer in the final round also indicated that my feedback was positive, but mentioned a further interview with the CTO would be scheduled for the following week after feedback collation. On the following Monday, the recruitment agency informed me that I did not pass the final round. From my perspective, the final round interview went very well, and the interviewer verbally gave me similar positive feedback.

Coding Technical
So, the interview had three rounds, and they were all technical. The first round kicked off with two Data Structures and Algorithms (DSA) questions. The first one was an array question, and the second was a dynamic programming (DP) one. After that, the interviewer dove into core subjects, starting with Database Management System (DBMS) stuff, mostly SQL, where they asked me to write some queries. The interview wrapped up with a discussion about my projects. In the second round, I faced two more DSA questions: a DP question first, followed by a simple linked list question. Then, there were more SQL queries, DBMS concepts, and some questions on Object-Oriented Programming (OOPs). The final round was heavily focused on development. They asked me about web development, then Operating Systems (OS), and finally DBMS. I ended up getting selected.
