The interview process was fairly straightforward.

It typically involved 3-4 rounds, depending on performance:

1st Round: 35 MCQs on C++ concepts, testing various aspects of pointers, pointer functions, and strings.

2nd Round: Five straightforward programming questions requiring implementation of standard C functions (e.g., substr(), atoi()), along with questions on strings, string reversal, word reversal, and linked lists.

3rd Round: Based on mistakes from the 2nd round. Expect in-depth questioning on C++ and OS concepts, including socket programming, TCP, IP fundamentals, and UDP concepts.

Asked me about my comfort zone and grilled me on it.
