Process
There are 3 technical interviews and 1 HR interview. It is a virtual interview.
In the first round, they ask technical questions based on Computer Networks. After qualifying, the candidate has to give the second round.
In the second round, I was asked about Operating Systems and 2 easy coding questions. In Operating Systems, they went very deep into all the concepts. I answered a few of them, but I understand that it was not up to the mark. So, unfortunately, I did not qualify in the second round.
Questions
Deadlock, Memory Management coding on strings and hash maps.
