The interview process was hassle-free, but the interviewer was hasty in forming judgments and didn't provide an opportunity for the interviewee to ask questions. Additionally, the interviewer seemed rushed to conclude the call, possibly because it was more of a "get to know you" session rather than a formal interview.

In technical interview round, I found it difficult. Basic sql questions and Linux questions. I was asked to find second highest salary from a table. Common utilities in Linux. Project related questions. Advanced c++ topics such as smart pointers, STL, etc
