Getting hired as an associate network engineer is no easy feat. You’ll likely have to ace some tough technical and behavioral interview questions to land the job. As someone who just graduated or is looking to break into the field, the interview can seem daunting. Where do you even begin preparing?
Not to worry! I’ve put together this comprehensive guide covering the 30 most common associate network engineer interview questions. With insights into what hiring managers want to hear and example responses, you’ll be ready to tackle any question that comes your way.
Why Interview Questions Matter
The interview is your chance to showcase both your technical abilities and soft skills With the right responses, you can demonstrate you have what it takes to succeed in the role and align with the company’s needs
On the other hand, improper answers to technical questions expose gaps in your knowledge. Failing to articulate your process clearly or provide sufficient detail leaves the interviewer unconvinced of your abilities.
Preparation is key to avoid common pitfalls. By anticipating likely questions, researching sample answers, and practicing, you can go into the interview feeling confident and ready to seal the deal.
Technical Interview Questions
Let’s start with some of the more common technical queries recruiters use to gauge your engineering skills:
1. What experience do you have with network design and implementation?
This open-ended question allows you to highlight your hands-on experience in designing, building, and managing network systems.
Discuss your understanding of technical concepts like VPNs, firewalls, routing protocols, and network hardware. Outline specific projects where you successfully executed tasks like:
- Determining network requirements
- Selecting appropriate technologies
- Configuring devices
- Implementing security measures
- Testing for functionality
Emphasize positives like improving efficiency, enhancing performance, and reducing costs. This shows the value you provide.
2. What is your experience with common network protocols like TCP/IP, FTP, and DNS?
Briefly explain the purpose and functionality of core protocols like TCP/IP (communication), FTP (file transfer), and DNS (domain name translation).
Highlight hands-on experience you have implementing and troubleshooting these protocols. Provide an example where your protocol knowledge helped identify or resolve a network issue.
Position yourself as someone able to leverage protocol expertise to manage network operations and infrastructure.
3. Explain how you would set up and configure a VLAN
Outline the key steps:
- Determine the purpose of the VLAN – e.g. improve security, reduce broadcast traffic
- Define VLAN ID and assign switch ports
- Configure routing protocol between VLANs
- Set access rules between VLANs
Discuss the benefits of VLAN implementation, like increased performance. This shows you understand and can communicate the value of technologies like VLANs.
4. How would you troubleshoot a slow network connection?
Emphasize a methodical, layered approach, for example:
- Identify extent of issue – users affected, locations, applications impacted
- Check cabling and hardware connections
- Review network configs and settings
- Monitor traffic and utilization patterns
- Use tools like ping tests to isolate faulty components
- Identify bottlenecks like low bandwidth or high usage
- Implement fixes like adding bandwidth, updating devices, optimizing traffic
Being systematic and detail-oriented is key when explaining technical troubleshooting.
5. What experience do you have securing networks and mitigating threats?
Demonstrate well-rounded knowledge of security concepts like:
- Firewalls – Describe how you implemented rules to filter traffic
- Encryption – Implemented protocols like WPA2 for wireless networks
- Access controls – Experience with ACLs, user permissions, VLANs
- Vulnerability testing – Scanning networks to identify risks
- Education – Trained users on threats like phishing and social engineering
Position yourself as someone able to implement layered security to protect network assets and information.

- Infrastructure monitoring – Nagios, Zabbix
- Log analysis – Splunk, ElasticStack
For each tool, briefly explain its purpose and how you leveraged it to provide network visibility and valuable insights.
7. Explain the difference between a router, switch, and hub
-
Router: Connects multiple networks together and routes traffic between them. Offers intelligent traffic management.
-
Switch: Connects devices within a network for local communication. Manages and filters traffic flow at data link layer.
-
Hub: Simple physical layer device that connects multiple Ethernet devices together in a single collision domain. Does not manage traffic flow intelligently.
Illustrate your understanding of the function and purpose of core networking hardware.
8. What skills does a network engineer need to have?
