Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about a time you built a tool or script that other engineers ended up relying on. What did it do and what happened when it broke?
What they are checking: whether their Python experience is production-grade automation versus disposable scripts
Tell me about the worst production outage you were on point for. What was the actual root cause and what changed afterward so it couldn't happen again.
What they are checking: ownership of postmortems and whether fixes were structural or just patches
Tell me about a time you had to push back on a deadline set by a vendor or field crew in a different time zone, where the schedule didn't match reality.
What they are checking: how they handle coordinating external parties under pressure without losing the timeline entirely
This job means real travel to towers, rooftops, and rural sites, sometimes on short notice, plus a follow-the-sun on-call rotation. What's your experience with that kind of schedule, and how do you think about the trade-offs?
What they are checking: honest self-assessment of whether the lifestyle demands of the role are sustainable for this person
What would you do
Say you've got a microwave link that's showing degraded SNR and rising BER but RSSI looks normal. How do you go about isolating the fault before you send anyone to the tower?
What they are checking: structured fault isolation skill and whether they know which telemetry actually points to which failure mode
A link you manage is down at 2am and the only person who can get to the tower is a subcontractor you've never worked with before. How do you get them to fix it correctly without you being on site?
What they are checking: ability to write and communicate field instructions clearly enough for someone else to execute reliably
If you found out a competitor's path between two data centers was faster than ours, how would you go about figuring out where the microseconds are being lost and whether it's worth chasing?
What they are checking: whether they think about latency as a measurable, defensible research problem, not just an engineering task
Tell me about a maintenance window you planned on a live, latency-sensitive network. What could have gone wrong and how did you protect against it?
What they are checking: rigor around change planning and outage notification when real money is on the line
About the work
Walk me through a wireless link you designed from scratch, from the link budget and Fresnel zone clearance to the antenna and mount geometry you chose.
What they are checking: whether the candidate has actually done RF path design end to end or just knows the vocabulary
How would you design a telemetry pipeline that collects RSSI, SNR, and BER from a mix of vendor radios and turns that into useful alerting instead of noise?
What they are checking: systems thinking around monitoring at scale and judgment about alert fatigue
Have you worked with FCC ULS or ASR data, or done frequency coordination for licensed microwave links? Walk me through how you'd research a new path before filing.
What they are checking: direct exposure to the specific regulatory datasets this job depends on, not just general RF knowledge
We're moving radio and link configuration into git so changes are reviewed and versioned. How would you structure that so a bad change gets caught before it hits a live path?
What they are checking: understanding of change control discipline in a low-tolerance production environment
Where do you see LLM or AI-assisted tooling actually being useful in network operations, and where do you think it would just get in the way?
What they are checking: realistic judgment about applying newer tooling versus chasing a buzzword
Explain DWDM channel planning and how it fits into a wireless network's overall path, as if you were teaching it to a new hire.
What they are checking: depth on the wireline half of the job, since candidates often only prepare for the RF side
