Example: When a network issue arises, I prioritise keeping everyone updated promptly and clearly, from the tech team to management and users. I set up quick check-ins to coordinate efforts and share progress, ensuring no one misses crucial info. For example, during a recent outage, regular updates helped prevent rumours and kept the focus on resolving the problem efficiently. Open, honest communication really helps maintain trust and control in those moments.

Questions like this assess your communication skills and ability to simplify technical information for diverse audiences. You need to describe a specific situation, explain the issue in easy-to-understand terms, and highlight how your explanation helped resolve the problem or improve understanding.

Example: In a previous role, I had to explain a network outage to our finance team. I compared the network to a city’s road system, where a blocked main road caused delays. This helped them understand the impact without technical jargon. I focused on what it meant for their work, reassuring them we were fixing it promptly. Keeping it relatable made the situation less stressful and built trust.

Hiring managers ask this question to see how well you manage projects and deliver results in a network environment. You need to clearly describe the project’s purpose, your leadership role, and the positive impact your work had on the network’s performance.

Example: Sure. In my previous role, I led a network upgrade across multiple offices to improve reliability and speed. I coordinated with vendors, scheduled maintenance to minimise downtime, and kept the team informed throughout. The project finished on time and boosted network performance by 30%, which significantly reduced support tickets and improved overall user satisfaction. It was rewarding to see the positive impact on daily operations.

What they want to understand is whether you grasp the core technical differences between TCP and UDP and can apply that knowledge to real-world networking scenarios. You should explain that TCP is connection-oriented and reliable, making it suitable for tasks like file transfers, while UDP is faster but less reliable, ideal for streaming or gaming where speed matters more than perfect delivery.

Example: Sure. TCP is connection-oriented, ensuring data arrives intact and in order, which makes it reliable but a bit slower. UDP, on the other hand, is connectionless—faster but without guaranteed delivery. So, for tasks like file transfers or emails, TCP is ideal. For live video streaming or online gaming, where speed matters more than perfect accuracy, UDP works better. Choosing between them depends on the balance between speed and reliability your network needs.

What they want to understand is how you inspire and maintain high performance in your team under challenging conditions. You need to say that you foster open communication, recognize individual contributions, and provide opportunities for growth to keep your team motivated and engaged.

Example: I believe in fostering open communication and recognising individual contributions to keep the team motivated. Regular check-ins help me understand their challenges, and I encourage learning opportunities to keep skills fresh. For example, I supported a colleague through certification which boosted their confidence and performance. Celebrating small wins together also creates a positive atmosphere where everyone feels valued and engaged.

Hiring managers ask this question to understand how you organize work to maintain network stability and efficiency. You need to explain how you assess task urgency and impact, delegate based on team strengths, and communicate regularly to keep everyone aligned.

Example: When managing my team’s workload, I first look at what tasks have the biggest impact or tightest deadlines. I then assign work based on each person’s strengths to keep things balanced and efficient. Regular check-ins help us stay aligned and quickly address any roadblocks. For example, during a recent network upgrade, this approach ensured timely completion without overwhelming anyone.

This question helps interviewers see if you are committed to continuous learning and staying current in a fast-evolving field. You need to say you regularly read industry resources and actively apply new knowledge to enhance network security and performance.

Example: I keep up by regularly reading industry blogs and whitepapers, attending webinars, and taking online courses to deepen my skills. I also participate in forums and local meetups, which helps me exchange insights with other professionals.

I’ve also handled VPN setups and maintained infrastructure for high-traffic environments, balancing performance with reliability. Each experience sharpened my ability to tailor solutions to different organisational needs.

Hiring managers ask this question to see if you understand how to keep a network reliable and minimize downtime during failures. You need to explain the importance of designing backup paths and automatic failover systems, and describe specific technologies or strategies you use to ensure continuous network availability.

Example: When managing network redundancy and failover, I focus on designing multiple pathways to ensure continuous connectivity. For example, using dual ISPs and redundant switches allows traffic to reroute instantly if one link fails. Regularly testing these systems helps spot any weaknesses early. The goal is to keep things seamless so users rarely notice any issues, maintaining reliable performance even during unexpected outages.

What they want to know is if you have verified skills that match the job requirements. You need to mention any relevant certifications like Cisco’s CCNA, CompTIA Network+, or similar credentials to show your qualifications.

Example: I hold certifications like Cisco’s CCNA and CompTIA Network+, which have given me a solid foundation in managing and troubleshooting complex networks. I've found that these qualifications really help when implementing security measures or optimizing network performance. For example, in my last role, applying what I learned from these courses helped reduce downtime significantly by quickly identifying bottlenecks and resolving issues.

Interviewers ask this question to assess your interpersonal skills and ability to maintain a productive team environment. You need to describe a specific situation, explain how you listened to all parties involved, and detail the steps you took to find a fair and effective solution.

Example: In a previous role, two team members disagreed over the best way to implement a network upgrade. I brought them together, encouraged open communication, and helped them focus on our shared goal rather than individual preferences. We combined their ideas into a practical plan, which improved both the network and the team’s collaboration. It reinforced the importance of listening and finding common ground.

Interviewers ask this to see if you understand the critical factors that impact a large network’s effectiveness and future growth. You need to explain assessing requirements and scalability, prioritizing security and reliability, and planning for manageability and performance optimization.

Example: When designing a network for a large enterprise, it’s important to understand the current and future needs to ensure it can grow smoothly. Security has to be built in from the start to protect sensitive data and maintain uptime. Equally, the network should be easy to manage and tuned to deliver fast, reliable performance. For example, segmenting the network can help contain issues and improve overall efficiency.

Interviewers ask this question to understand how you proactively maintain network efficiency and ensure smooth operations. You need to explain that you analyze performance data with monitoring tools to identify bottlenecks, apply targeted solutions like optimizing protocols or upgrading hardware, and continuously monitor the network to prevent future issues.

Example: When I notice network slowdowns, I start by reviewing performance metrics to find the root cause, whether it’s hardware limitations or traffic spikes. Then, I apply targeted fixes like optimizing configurations or upgrading equipment. I also keep an eye on the network continuously, using monitoring tools to catch issues early and adjust as needed, ensuring smooth operation well before problems escalate.
