Next, he asked questions from CN, i.e the OSI/TCP model description, difference between switches, routers. Functions of each layers of OSI, and last, difference between TCP/UDP, how a req is transfered from clinet to server, and back to client.

Next He asked what are micro services, but i haven't read about system design, so i said honestly, i haven't prepared for system design, he was satisfied, since my previous 40 mins went really good.

At last, he ased questions from OOPs, i.e the polymorphism, inheritence, difference b/w overloading and overriding, Virtual Functions. 

All were at easy levels, they haven't gone in depth.
