Google Network Engineer interviews, as candidates describe them, focus on networking depth: OSI and packet flow, TCP internals, BGP and OSPF, VLANs, and outage troubleshooting, with behavioral rounds. Loop length varies between reports.

Three candidates describe Google Network Engineer loops that differ in length but share a focus on explaining how networks actually behave, not naming protocols. One candidate described a three-round process (hardware and OS, networking, behavioral). Another reported nine interviews, five technical and four behavioral. A third described at least two technical conversations.
Packet flow comes up in every account. One candidate was asked to walk through what happens when a device reaches google.com, layer by layer, covering DNS, the TCP handshake, TLS and routing. Another was asked how ping and traceroute work step by step and how traceroute discovers hops. A third was asked for packet flow in detail and to name the six TCP header flags and explain each one.
Routing protocols also appear: BGP and OSPF were mentioned by two candidates, and one said the BGP questions went deeper than CCNA-level preparation. Other reported topics include stateful firewalls, VLAN isolation, spine-leaf design, redundant power supplies, DDoS basics, and a multi-site outage scenario where interviewers wanted to hear how you would isolate and contain the problem. One candidate also saw easy Python and SQL questions.
The experiences were mixed: one candidate declined an offer and two did not receive one. One of the latter called the process disorganized. Prepare to narrate your reasoning aloud, and study mechanics rather than certification-level definitions.

Synthesized from candidate reports. Individual experiences may vary.
One candidate reports being contacted by a recruiter about a Network Engineer role and mentioning a software-leaning background on the screening call. The recruiter still encouraged an application. Other candidates did not describe a screen, so treat this as one person's experience.
One candidate describes this round as relatively easy. Questions covered connecting to a Cisco switch in a rack, accessing a home router, redundant dual power supplies, network troubleshooting tools, defining scalability and explaining a DDoS attack. Other candidates did not describe a separate round like this.
Candidates report conceptual and deep-dive networking questions: the OSI model, packet flow, DNS, TCP/IP, TCP header flags, ping and traceroute, stateful firewalls, VLANs, spine-leaf, BGP and OSPF. One candidate found the second round at CCNP depth. Expect follow-ups into specific layers.
A candidate with a nine-interview loop describes open-ended scenarios, including a major multi-site outage where they had to explain immediate isolation and containment. They say interviewers valued the reasoning voiced as much as a single correct answer. Some rounds also reportedly included easy Python and SQL.
Two candidates mention behavioral rounds. One described a conversational style focused on past projects, decisions and why one approach was chosen over another. Another listed behavioral as the third of three rounds. Candidates reported outcomes ranging from a rejection right after the networking round to a declined offer.
