Technical Coding Behavioral
For a network engineer role, it usually kicks off with a quick phone chat to see if your tech background, certs, and experience with network gear and protocols line up. Then, you'll dive into a technical interview where you'll tackle some real network problems, maybe even getting hands-on with device configs or network troubleshooting. Expect questions about routing, switching, security, subnetting, and protocols like BGP or OSPF. Sometimes they throw in a lab test too. The last part is often a behavioral chat to check out how you handle working with others, communicating, and solving problems. It's all about seeing if you've got the tech chops and if you'll fit in.
