The first phone interview consisted of very basic questions related to networking, such as the difference between TCP and UDP, the ICMP protocol, ARP, and DHCP.

This was followed by a two-hour onsite interview in Santa Clara, conducted by four people. They asked about the same topics, delved into subnetting in detail, and requested simple Python code examples.

I was called for another onsite interview round because there was a tie. This interview was conducted by three other people.

The interview went excellently with their senior network engineer and Tech Lead, but at the end, a senior Development Manager (IIT and Berkeley) asked me confusing questions and stated I needed to work more on the basics.
