Round 3: Technical Interview

The Interviewer asked me which Language I’m comfortable with and I told him C++ and this was a pen-paper-based coding interview.

1. Basic questions of Pointer and double pointer and a question of using pointers to display elements of an array
2. Questions on Object-Oriented Programming: Access Modifiers, Constructors, Friend Class, Scope Resolution operator, this pointer, and the 4 Pillars of OOP. He also asked me to write code for the implementation of these concepts. Overall, the questions were easy.
3. Then he started to ask some questions on DSA:
   1. Rotate an array
   2. Find 2nd largest no in an array
   3. Concatenation of Array
   4. Question on singlsingle and doubly LinkedList
   5. Write code for the Quicksort algorithm to sort an array and explain time complexities
4. After this, he started to interview on Computer Networks.     
   1. Explain OSI Model and all the layers
   2. IP Classful Addressing. there was a question where I had to identify the class of a given IP with no of host. also, I had to calculate IP waste.
   3. What we are using on the internet TCP/IP or OSI?
   4. Explain Three-way handshake of TCP
   5. Autonomous systems
   6. Explain Border Gateway Protocol
   7. why do we use Routing Protocols
   8. what is the split horizon and what solution for it
   9. How ARP works
   10. What is MTU? how the packet gets fragmented and what is offset?
5. Additionally, since my resume featured a Project on Computer Networks, he asked a few questions on socket programming, which might not be asked if not mentioned in the resume.

Round 4: HR

After the final HR round, I got selected for the R&D Software Intern Role at Keysight Technologies and received the offer letter within a week. For this profile, a strong grasp of Computer Networks, along with a clear understanding of DSA and OOP fundamentals, is essential. Special thanks to Kiran Sir and Nitisha Ma’am for their excellent teaching of CN.
