Answer Example: "Yes, I have extensive experience working with legacy systems. I have worked with many different types of legacy systems, including Cisco, Juniper, and HP ProCurve. In each instance, I took the time to understand the architecture of the system and how it works. This allowed me to effectively troubleshoot issues and implement changes without impacting the overall functionality of the legacy system."
This question can help the interviewer determine how you make decisions about the reliability of information and whether you have a process for doing so. Use examples from past experiences where you researched products or services and determined their validity.
Answer Example: "When researching new products to recommend to clients, I always look for reliable sources of information. I always start by doing an extensive search of the product or service name in search engines like Google or Bing to see what comes up. I then look at the top results to see if they are reputable websites or blogs that provide credible information. If I find any negative reviews or complaints about the product or service, I make sure to read them thoroughly so that I can determine if they are valid or not. Finally, I always check the vendor’s website to see if they provide any information about the product or service that can help me make an informed decision."
This question is an opportunity to show your problem-solving skills and ability to analyze data. When answering this question, make sure that you explain how you would use the information provided by the interviewer to make an informed decision about how to improve customer satisfaction levels.
