Interview
The interview process comprised of four rounds of interviews:
1. Coding Round - I
2. Coding Round - II
3. Techno-Managerial Round
4. Executive Round
For the coding rounds, the focus was primarily on logic building and optimization strategies with trade-offs of space and time.
In the Techno-managerial round, CS fundamentals such as concurrency, database indexing and normalization along with some knowledge of High Level Design were evaluated.
In the final Executive Round, general HR questions and some situation based questions were asked.
