It was an on-campus interview. Initially, we had an online examination. Questions ranged from C programming to microprocessors, and from MOSFETs to subnet masking. There were also a few aptitude questions, which were a little bit tough. Out of 36 people who appeared for the online test, 15 were shortlisted.

After that, we had two rounds of interviews.

In my first technical round interview, I was asked some very basic C questions. When I say basic, I mean very basic – you should know how memory allocation works in C.

I was asked the following questions:

1. How to find out the size of a structure without using the sizeof() function.
2. What are holes in C?
3. What is inheritance?
4. What are copy constructors and virtual functions?
5. C program to reverse a linked list.

After that, I had another round. I'm not sure whether that round was technical or HR. My interviewer grilled me about my low CGPA for around 50 minutes. He just asked me to write a Python program to print prime numbers between 1 and 100 (since I mentioned Python in my resume). He also asked what I know about software testing and whether I am willing to do software testing at CISCO. End of the day, it was all about CGPA.

They selected two students with the highest and second highest CGPA.
