1. Can you tell us about a particularly challenging incident you had to handle and how you
resolved it?
Answer
One particularly challenging incident I had to handle involved a major network outage at a large
financial institution. The incident occurred during a critical period when the institution was
processing a large volume of transactions. The outage affected all systems, including core
banking, internet/mobile banking, and e-payments.
To resolve the issue, I took the following steps:
Identified the root cause: I worked with the network team to identify the cause of the outage.
We discovered that a critical network device had failed, causing a cascading effect on the entire
network.
Contained the issue: I immediately implemented a workaround to restore some critical services
while the team worked on a permanent solution. This involved rerouting traffic to alternative
network devices and implementing temporary patches to critical systems.
Communicated with stakeholders: I kept all stakeholders informed of the situation and provided
regular updates on the progress of the resolution. This included the IT team, the business units
affected by the outage, and senior management.
Worked with vendors: I coordinated with vendors to provide additional support and resources to
help resolve the issue. This included engaging with network equipment vendors to provide
replacement devices and working with software vendors to provide temporary patches.
Implemented a permanent solution: Once the temporary solution was in place, I worked with
the network team to implement a permanent solution to prevent a similar incident from
occurring in the future. This involved upgrading critical network devices and implementing
additional redundancy measures.
Conducted a post-incident review: After the incident was resolved, I conducted a post-incident
review to identify any areas for improvement and implement additional measures to prevent
similar incidents in the future.
2. Can you give an example of how you have used your critical thinking and problem-solving
skills to identify and resolve an issue?
Answer
Throughout the process, I employed critical thinking skills to analyze the situation, identify
potential solutions, and evaluate the implications and consequences. By using a logical and
systematic approach, I was able to identify and resolve the network congestion issue, which
improved network performance and reduced downtime for critical applications.
I took the following steps:
Analyzed the situation: I gathered and reviewed as much information as possible to understand
the root cause of the network congestion. This included reviewing network traffic logs,
conducting network analysis, and speaking with other network engineers.
Identified available solutions: Based on my analysis, I identified several potential solutions to
address the network congestion. These included upgrading network hardware, implementing
network optimization techniques, and reconfiguring network routing.
Evaluated the implications and consequences: For each potential solution, I evaluated the
implications and consequences to determine the best course of action. This included considering
the cost, complexity, and potential impact on other network services.
Selected the solution: After evaluating the potential solutions, I selected the solution that
offered the best balance of cost, complexity, and impact. In this case, I recommended
implementing network optimization techniques and reconfiguring network routing.
Implemented the solution: I worked with the network team to implement the selected solution.
This involved configuring network devices, testing the network, and monitoring network
performance to ensure that the issue was resolved.
