Highlight any feedback or results that demonstrated the customer’s satisfaction with your work.

Example: “On a particularly tough job, I was installing fiber optic lines in a residential neighborhood where one customer was experiencing repeated service interruptions. They had already been frustrated by prior issues and were skeptical about the repair process. I made it a point to first listen to all their concerns and reassure them that I was committed to resolving the issue once and for all.

After thoroughly inspecting the existing installation, I discovered that the problem stemmed from a poorly installed junction box susceptible to weather conditions. I explained the situation to the customer in straightforward terms, outlining what I’d do to fix it and how it would prevent future issues. I replaced the faulty equipment, tested the connection multiple times, and stayed to ensure everything was working perfectly. Before leaving, I provided them with direct contact information for any further issues and followed up a week later to confirm that the service was stable. Their gratitude and relief were clear indicators of their satisfaction, and they even left positive feedback for the company.”

23. In what scenarios would you use mechanical splicing over fusion splicing?

Understanding the scenarios in which mechanical splicing is preferable over fusion splicing reveals not only a candidate’s technical knowledge but also their ability to make cost-effective and practical decisions in the field. Mechanical splicing, while generally less permanent and slightly more prone to signal loss, is often quicker and less expensive, making it ideal for temporary fixes or situations where equipment for fusion splicing isn’t available. This question assesses a technician’s adaptability and resourcefulness in varying operational contexts, which is crucial for maintaining network integrity and efficiency under different circumstances.

How to Answer: Highlight specific situations where mechanical splicing is advantageous, such as emergency repairs or environments with limited access to advanced equipment. Mention any relevant experiences where you successfully used mechanical splicing to maintain service continuity.

Example: “I’d use mechanical splicing primarily in scenarios where speed and cost are crucial factors. For instance, if there’s a need for a quick temporary fix or in situations where the budget doesn’t allow for the purchase of expensive fusion splicing equipment, mechanical splicing is the go-to method. It’s also useful in emergency repairs where the main objective is to restore service as quickly as possible, even if it’s just a temporary solution until a more permanent fix can be arranged.

In a previous role, I encountered a situation where a critical fiber link was damaged during a construction project, and we needed to restore service immediately. With limited resources on hand, I opted for mechanical splicing to ensure minimal downtime. While it wasn’t a permanent solution, it allowed us to get the network back up and running swiftly, and we could schedule a more durable fusion splice repair for a later time when we had the proper equipment available.”
