The job of a site reliability engineer spans the functions of Google's DevOps and IT infrastructure groups. One of the elements both of these teams needs to address is the network topography. Knowing about TCP and its connection states will demonstrate your qualifications for this role and may even set you apart from other candidates.

"Transmission Control Protocol, or TCP, is part of the Internet protocol suite. It is often referred to as TCP/IP. TCP/IP controls the transmission of data across the network, ensuring that the right information is exchanged between the network nodes. Common TCP connection states include: LISTEN- when the server is listening for traffic, SYNC-SENT- after a request is sent and the servicer is waiting for a response, SYN-RECEIVED- when the servicer is waiting for a response to an ACK signal and ESTABLISHED- which indicates that a three-way TCP connection has finished."
