What is the interview process for a Network Engineer role at F5 Networks, and what does each stage test?

The process starts with a recruiter screen, then a technical phone interview with a team lead or senior engineer. If you pass, you move into a multi-stage onsite or virtual loop with technical deep-dives and behavioral discussions with managers and peers. The loop is designed to test your knowledge across the networking stack, from Layer 2 up through Layer 7, alongside your communication and collaboration.

How hard are F5 Networks interviews for a Network Engineer role, and what offer rate do candidates report?

In candidate-reported results from 17 interviews, the most common difficulty level was average. Candidates reported a 47% offer rate, which gives a sense of how often the process ends in an offer after going through the stages.

What technical topics do F5 Networks test for Network Engineer interviews?

Expect foundational networking and protocol questions, including OSI model (layered networking), TCP/IP fundamentals, routing table inspection, and network troubleshooting. You should also be ready for application and security topics like the SSL/TLS handshake, DNS, and HTTPS, plus HTTP fundamentals. The guide also emphasizes deep-dive capability, meaning you should explain not just the “what,” but the mechanics at the packet or command level.

Which Network Engineer interview questions are most likely at F5 Networks?

From the public sample questions, you should be able to answer “How Switches Forward Traffic” and “Ping vs Traceroute.” The guide also lists representative categories that align with these themes, such as explaining OSI layers, describing how switching works, and troubleshooting scenarios like diagnosing a slow network.

What Linux and command-line skills are important for a Network Engineer interview at F5 Networks?

You are expected to be comfortable with Linux basics that support troubleshooting and operations. The guide specifically calls out routing table checking in Linux, listing running processes, and knowing where logs typically live in UNIX systems. It also highlights understanding differences between system log locations like /var/log/syslog and /var/log/messages.

How much does an F5 Networks Network Engineer get paid, and what factors change compensation?

The information provided does not include candidate-reported compensation for the F5 Networks Network Engineer role. It does confirm that pay can vary by level and location, but no dollar figures are given here for this role.

Difficult Positive Japan

One interview session ended up lasting about four and a half hours. It wasn’t just coding—it was a scenario meant to evaluate a broad set of skills. I covered technical topics like TCP/IP, UDP, DNS, and HTTP/HTTPS, and then I was pulled into soft-skill evaluation, escalation skills, and troubleshooting.

That breadth made it feel difficult in a very specific way: even if I knew the topics, the time and scope forced me to stay sharp and structured the whole way through. I didn’t get an offer, and the biggest reflection I have is how exhausting it was to be assessed across so many dimensions in a single long scenario.

Average Positive London, England

I went through two sessions of technical interviews, and each session had two interviewers. The first session was manager-focused but still heavily technical: it leaned into network-related questions and felt grounded in core knowledge. The setup was pretty direct—two engineers running the conversation—and I remember thinking that reviewing fundamentals like the OSI model and TCP/IP would’ve helped.

The second session was more diverse and shifted toward computing systems with a lot of Linux-based questioning. What stood out was how different it felt from the networking-heavy first part, even though it was still in the same technical track. When the manager session was included, it felt like they were already fairly far along in the selection, because it turned into more of a “fit and conversation” checkpoint than the earliest gate.
