Interview Questions with Model Answers

Review these common interview questions with answers to prepare for a successful network engineer interview:

Discuss static versus dynamic IP addressing.

This is a basic technical question that network engineers, even those with entry-level experience, should have enough knowledge to answer. An employer might ask this question to make sure you’re confident with the basics of networking before going into deeper questions about your experience and knowledge.

Example: “The variance among a static and a dynamic IP address is the flexibility of structure. In a static IP address, a device always uses the same IP address when accessing the Internet. In contrast, a dynamic IP address can change regularly and more frequently for home devices compared to businesses.”

Have you ever had to give a technical presentation to an audience with no technical experience? Tell us who the audience was and how you presented the materials?

As a network engineer, you may be required to give presentations to network users, other engineers, or members of the executive team. While some individuals, especially those who work in information technology or are fellow engineers, are likely to understand the industry jargon and details you provide in your presentation, not all employees will. It is important to be able to effectively present information to everyone, regardless of their networking knowledge.

Example: “I used to give presentations to non-technical audience members. I had to communicate everything from network updates to system upgrades and how it might affect traffic. I also discussed what employees can do to support the company network and the benefits of knowing networking best practices no matter what your job entails.

What is your experience working with a development team?

It is increasingly common for network and development teams to work together to support each other in a common goal. The interviewer may ask you this question to gain insight into how you interacted with other key teams in your previous roles and to understand more about your thoughts on cross-team collaboration. Before answering, pause, plan your answer, and consider adding an example.

Example: “In my last spot, I functioned closely with the DevOps teams to make sure that the starter of diverse software did not adversely impact our network optimization. We communicated everything during software development, so my team knew what to expect and what network resources, which the team would need to effectively launch the software to all users.”

How do you want to stay up to date with new trends and new technologies in network engineering?

The hiring manager will ask you this question to see how dedicated you are to the field, so it’s important to answer honestly and show how interested you are in further expanding your knowledge of network engineering.

Example: “I know how important it is to stay up to date with news and trends in our industry because it is constantly changing, so I have several ways to stay informed. I subscribe to and read industry news publications and blogs and regularly listen to relevant podcasts. I am also part of a network engineer association. We share industry news and I attend conferences, webinars and training that the association provides to members.”
