Interview Questions for Technical Support Professional Certification (TSP)

My troubleshooting methodology follows a structured approach, often described as the “five whys.” I begin by clearly identifying the problem. This involves active listening to the user, gathering all relevant information, and confirming the issue’s symptoms. I then systematically work through possible causes, asking “why” repeatedly until I reach the root cause. This helps avoid addressing only symptoms.

• Identify the Problem: Precisely define the issue. For example, instead of “My computer is slow,” I’d ask for specifics: “How slow? What applications are slow? When did it start?”
• Gather Information: Collect data like error messages, logs, system specifications, and recent changes.
• Develop a Hypothesis: Based on the gathered information, I formulate possible causes.
• Test the Hypothesis: I systematically test each hypothesis, isolating variables to pinpoint the root cause. For example, I might temporarily disable a suspected application or run a system diagnostic.
• Implement a Solution: Once the root cause is identified, I implement the appropriate solution, which may involve configuration changes, software updates, or hardware replacement.
• Verify the Solution: I confirm that the solution has resolved the problem and that the system is functioning correctly. I also document the issue and resolution for future reference.

For instance, a user reported their email client wasn’t sending emails. By asking “why,” I determined the issue stemmed from incorrect SMTP server settings, not a malfunctioning client. This systematic approach ensures efficient and accurate troubleshooting.

I’m proficient with various remote troubleshooting tools, including TeamViewer, AnyDesk, and LogMeIn. These tools allow me to remotely access a user’s system, view their screen, control their mouse and keyboard, and transfer files.
