Question 1
Specific questions about processes that should be written down.
Great interview experience! The focus was on networking fundamentals like LAN, OSPF, TCP/IP, and the OSI model. The questions were technical but fair, testing both theoretical knowledge and practical application. A great way to assess networking expertise.
