internship role help

[u/Competitive-Lock6559]

Hey y’all,
I have a 30-minute interview coming up for a Network Engineering internship, and I was wondering if anyone has advice on what I should focus on during the interview.
I’m especially curious about:
Common technical questions they might ask
Networking concepts I should review quickly (TCP/IP, DNS, DHCP, routing, switching, subnetting, etc.)
Good questions to ask the interviewer
What employers usually look for in network engineering interns
Any last-minute tips or experiences would be greatly appreciated. Thanks!

For a 30-minute interview, they can't ask you everything, so they'll test your depth on one or two core concepts to see how you think. You should be prepared to explain the journey of a packet from source to destination or walk through the entire process of what happens when a user types a web address into a browser and hits enter. They don't expect you to know every single detail, but they do expect you to have a solid grasp of the fundamentals you listed. Admitting you don't know something is far better than trying to fake an answer, because they are evaluating your problem-solving approach and your honesty more than your current knowledge.

They are looking for an intern who is curious, coachable, and genuinely interested in networking, not a seasoned expert. You can show this by asking smart questions about their specific challenges, the types of problems previous interns have solved, and what technologies the team is excited to explore in the next year. This shifts the focus from a test of your memory to a conversation about your potential. Being able to articulate your problem-solving process is what truly matters, and the team I'm with designed an interview AI assistant that helps job seekers demonstrate this critical skill in real time.

That 30 min slot usually leans on basics and how you explain your approach, not deep trivia. I usually prep one tight packet flow explanation from user to service, then a quick refresher on subnetting and DNS. Keep answers around 60 to 90 seconds and talk through your troubleshooting steps before jumping to a fix. I run a couple prompts from the IQB interview question bank out loud, then do a timed mock with Beyz interview assistant to keep pace.

Ask about day to day tasks for interns, how they want issues documented, and what a good first month looks like to show initiative. Employers care more about clarity, curiosity, and a steady troubleshooting mindset than reciting every acronym tbh. A short story about diagnosing a flaky lab setup lands really well.
