Tell me about yourself and your experience as a cable technician

Start with your current role and the most relevant field experience that aligns with the job, focusing on the last 5 to 10 years. Highlight specific responsibilities like installations, maintenance, or working with fiber and coax, and explain why this role matches your skills and interests. Give a brief example of a representative day, for example running drops, testing signal levels, and documenting work orders to show you understand the daily flow. Practice a 60 to 90 second version so you stay concise and avoid reciting your resume verbatim.

What tools and equipment are you most comfortable using on the job?

Explain the core tools you use regularly and what you use them for, such as multimeters for continuity checks, signal level meters for verifying RF levels, compression tools and crimpers for connectors, and fiber test equipment for fiber runs. Be specific about brands or models only if asked, and focus on function and safety when describing your experience. Include a short example of a situation where the right tool saved time, for example using an OTDR to locate a fiber fault instead of replacing large sections of cable. Avoid claiming you can use every tool if you have limited experience; be honest about what you can do independently and where you would seek guidance.

How do you troubleshoot signal loss on a subscriber's line?

Describe a clear step-by-step approach: check the customer equipment and in-home wiring, verify signal at the tap or splitter, inspect connectors and splices, and then test at intermediate distribution points. Emphasize systematic testing so you isolate whether the issue is inside the home, on the drop, or in the network feed. Offer a short example such as finding a loose F-connector at the wall outlet and showing how re-terminating the connector restored levels. Mention common mistakes to avoid, like replacing equipment before measuring signal or skipping documentation of test results.

Describe your experience with coaxial cable splicing and termination

Explain the procedures you follow for clean splices and reliable terminations, including preparing the cable, using proper stripping tools, installing compression connectors, and verifying with a signal meter. Stress adherence to manufacturer specs and weatherproofing outdoor terminations to prevent future faults. Share an example where re-terminating a damaged connector resolved intermittent service, and note that you always test after the repair to confirm stability. Avoid rushing terminations or cutting corners on shielding, since small mistakes can lead to signal issues later.

What is your process for installing new cable drops in a customer's home?

Outline the steps you take from site survey to completion: assess route and obstacles, obtain customer consent for routing, drill and fish cable where needed, terminate and test, and leave documentation and clean workspaces. Emphasize communication with the customer about placement and any potential interruptions during the install. Provide a concrete example like planning cable routing to avoid HVAC ducts and using grommets where the cable passes through a wall for a tidy finish. Mention that you always verify signal and explain basic operation to the customer before leaving.

How do you prioritize multiple service calls in the field?

Describe how you triage calls based on safety, outage impact, and SLAs, handling complete outages and safety hazards first, then urgent customer-affecting issues, followed by routine installs. Mention using dispatch guidance and communicating with dispatch when travel time or parts impact scheduling. Give an example of re-prioritizing your day when a neighborhood outage required immediate attention while you were scheduled for an install, and explain how you kept customers informed. Avoid overcommitting to unrealistic timelines; be transparent about travel and repair windows.

How do you handle an upset or frustrated customer on site?

Start by listening and acknowledging their frustration, then quickly explain what you will check and the likely next steps so expectations are clear. Keep your tone calm and professional, and if you need time to diagnose, give the customer a realistic timeline and offer to follow up with updates. Share a short example where calming a customer and explaining the test findings led to cooperation and a successful repair. Avoid technical jargon with customers; translate findings into simple terms they can understand.

What safety procedures do you follow while working on aerial or underground cables?

List key safety practices such as verifying utility locates before digging, using personal protective equipment, following fall protection rules for aerial work, and de-energizing equipment when required. Emphasize adherence to company safety protocols and local regulations to reduce risk to yourself and customers. Give an example like completing a pre-job safety check and setting up traffic or site barriers before working near a roadway, which prevented an incident. Avoid taking shortcuts on PPE or skipping permit requirements.

How do you read and interpret wiring diagrams or network maps?

Explain that you first identify endpoints, distribution points, and any labeled splitters or amplifiers, then trace the signal path to locate likely fault zones. Use diagrams in combination with field measurements to confirm where the problem lies and to plan efficient repairs or installations. Provide a concrete technique such as marking the diagram as you test locations, which speeds up repeated troubleshooting on complex jobs. Avoid relying solely on maps if they are outdated; always verify in the field.

Have you worked with fiber optic cables, and what steps do you take when testing fiber?

Describe basic fiber handling and testing steps such as cleaning connectors, performing visual inspections, using an optical power meter or OTDR to verify continuity and loss, and protecting fibers from bends and stress. Highlight that fiber requires careful cleaning and handling to avoid insertion loss from contamination or microbends. Give an example where cleaning a connector and re-testing showed a large improvement in power levels, saving a fiber replacement. Note common pitfalls like skipping inspection or using improper cleaning methods that can make the problem worse.

Tell me about a time you resolved a major service outage under pressure

Situation: A neighborhood experienced a service outage during peak hours and many customers reported loss of service. Task: As the on-call technician, you needed to locate the fault quickly and restore service while keeping customers informed. Action: You coordinated with dispatch, used signal meters to narrow the fault to a distribution amplifier, swapped in a tested spare, and then inspected downstream drops to confirm stability. Result: Service was restored within the allocated window, customer complaints dropped for that outage, and you updated documentation so future incidents would reference the root cause.

Describe a time you had to deal with a difficult customer who threatened to cancel service

Situation: A long-time customer was frustrated by repeated intermittent issues and demanded a refund or cancelation. Task: Your task was to de-escalate the situation, identify the underlying issue, and restore confidence in the service. Action: You listened to the customer without interrupting, explained the diagnostic steps you would take, completed a thorough inspection of in-home wiring and external connections, and replaced a damaged drop cable. Result: The customer agreed to continue service, reported improved reliability, and later praised the clear communication in a follow-up call.

Give an example of a time you improved a process that saved time or reduced repeat visits

Situation: Your team was making repeat visits to homes for the same connector failure due to inconsistent termination practices. Task: You needed to reduce repeat calls and standardize the termination process across the crew. Action: You proposed and demonstrated a standardized termination checklist, trained coworkers on proper compression technique, and introduced an inspection step before leaving each job. Result: Repeat visits for that failure type dropped significantly, and techs reported faster handoffs and fewer callbacks.
