Tell me about a situation that required you to dig deep to get to the root cause. How did you know you were focusing on the right things? What was the outcome? Would you have done anything differently?
Situation: In my current role, I encountered a problem where multiple tickets were raised for several EBS instances with the same issue. When I investigated, I found that three of these tickets had incorrect parts ordered and allocated, which was causing delays in resolving the issues.
Task: My task was to identify the root cause of the problem to prevent similar issues in the future. Since the root cause was not immediately obvious, I needed to dig deep to find out exactly what was going wrong.
Action: I started by reviewing the comments and history on similar tickets, looking for patterns and potential triggers for this recurring issue. I found two key problems: first, the automated system had allocated incorrect parts to each ticket, and second, the issue wasn’t with the parts themselves. It turned out that the card itself wasn’t communicating properly with the drive, so replacing the card rather than the drive was the actual solution.
Outcome: After identifying these issues, I adjusted the ticketing and allocation process to ensure the correct parts were matched to each case. This change helped prevent future misallocations and improved our response time on similar tickets. The solution worked well, and we saw a reduction in similar errors afterward.
Reflection: Looking back, I would have checked the allocation system parameters earlier to verify accuracy. This experience reinforced the importance of thorough root-cause analysis and paying attention to how automated processes handle assignments.
This answer demonstrates your ability to investigate thoroughly, identify the underlying issue, and take action to improve processes.
Here’s how to answer those specific parts for your situation:
How I knew I was focusing on the right things: I knew I was on the right track because I started seeing patterns across similar tickets and realized that the issue wasn’t random. By looking at each part of the ticketing process, including how parts were allocated, I was able to pinpoint that automation might be assigning the wrong parts. This led me to double-check the root of the problem: the card itself rather than the drive. Recognizing this pattern confirmed that I was focusing on the right areas to solve the issue effectively.
Outcome: Once I identified the root causes—both the incorrect allocation by automation and the actual problem with the card—I implemented changes to the process. This resulted in more accurate ticket handling and improved our troubleshooting efficiency. We saw a significant reduction in similar misallocations, which led to faster issue resolution and fewer delays.
Would I have done anything differently? In hindsight, I would have started by reviewing the allocation parameters of our automated system earlier. This experience taught me the importance of verifying automated assignments to ensure accuracy, especially for recurring issues. Next time, I’ll focus on checking both human and automated processes right from the start.

Situation: We had an issue where several hosts appeared to have power (motherboard powered on, dongle functioning, etc.), but the power button was blinking, and the hosts wouldn’t turn on. This created a major disruption, as it affected multiple hosts and slowed down our workflow.
Task: My task was to thoroughly investigate and identify the root cause of the issue to find a solution. Given that this was a recurring problem affecting several hosts, I needed to dig deep to uncover the underlying cause.
Action: I started by carefully examining the motherboards of the affected hosts. I compared the lights on the motherboard to those of a healthy, functioning host. I noticed that the CPLD (Complex Programmable Logic Device) lights on the affected boards were different. This observation made me think that the issue could be related to the CPLD, so I decided to dive deeper into this component. I conducted further research and found that the problem indeed lay with the CPLD, which was malfunctioning. Recognizing the severity of the issue, I escalated it to the appropriate team that had the expertise to handle this specific hardware issue.
Outcome: By identifying that the problem was tied to the CPLD and escalating it to the right team, we were able to resolve the issue and restore the affected hosts to full functionality. The action helped prevent further downtime and ensured that our systems returned to normal operations.
What I would do differently: In hindsight, I would have started my investigation by checking the CPLD lights earlier in the process. This experience taught me the importance of looking beyond the obvious symptoms and diving deep into specific technical details to identify the root cause. In future troubleshooting, I’ll focus on examining all the components more systematically from the start.

Tell me about a specific metric you have used to identify a need for a change in your department. Did you create the metric or was it already available? How did this and other information influence the change? What was the outcome of this change?
In my role working on the digitalization of a cab company, I developed a database system that allowed the manager to track a driver’s revenue in real time. This system was created to help manage and analyze the earnings of each driver more efficiently.
My task was to implement a way for the manager to monitor the revenue of each driver live and enable them to filter the data by day or across a longer period. I needed to ensure that the manager could easily track performance and identify any discrepancies or issues with earnings.
I created a revenue tracking metric within the database that displayed real-time earnings data. This metric allowed the manager to filter earnings by day, week, or month, making it easier to spot patterns or issues, such as drivers not completing shifts or discrepancies in earnings due to system errors. By gathering and analyzing this data, we were able to identify areas where revenue tracking could be more accurate or where drivers needed more support in reaching their targets.
The implementation of this metric helped the manager stay on top of the drivers' earnings and provided clear insights into daily and overall performance. It allowed for quicker detection of any issues with the system or discrepancies in revenue, and it also helped the company make data-driven decisions about driver performance and compensation. This change led to improved transparency and efficiency in the company's operations, which ultimately improved driver satisfaction and operational oversight.
This experience reinforced the value of using data and metrics to drive decision-making. By creating a system that allowed for real-time tracking and filtering, I learned that providing easy access to key performance indicators (KPIs) can lead to more informed, timely decisions. If I had to do it again, I would set up even more detailed metrics earlier on to capture a wider range of data points and anticipate any potential issues.
