What a Network Engineer Interview Actually Tests

A Network Engineer loop tests routing and switching at the mechanism level — BGP path selection and route reflection, OSPF adjacency troubleshooting, VLAN and STP design, asymmetric routing failure modes — not just protocol definitions. Expect live troubleshooting scenarios where the interviewer deliberately under-specifies the problem and watches how you scope it before proposing a fix, plus enough automation fluency to discuss repeatability, validation, and rollback even if the role itself isn't writing production code. The candidates who stand out explain mechanism, operational consequence, and what they'd check next — in that order — rather than reciting a definition and stopping.

What "L5" Means at Google

At L6 (senior), the bar shifts from 'is the design correct' to 'did you notice the problem was bigger than stated' — scope, blast radius, and unprompted trade-off articulation matter as much as the technical answer itself. Under-specified questions are often deliberate; stating a reasonable assumption and moving on reads stronger than asking the interviewer to fill in every detail.
