Welcome to Network Interview (owned by AAR Technosolutions)— your single destination to prepare for your next interview and build a career in networking, security, and IT infrastructure.
Since 2015, we’ve been helping students, working professionals, and career-changers navigate the fast-moving world of networking and IT. What started as a resource for interview preparation has grown into a comprehensive knowledge hub covering everything from core networking fundamentals to enterprise security, cloud & virtualization, routing and switching, and emerging technologies.
What We Do
We publish in-depth blogs, interview Q&As, cheat sheets, mind maps, and video courses across a wide range of topics — including firewalls (Palo Alto, Fortinet, Checkpoint, Cisco, Juniper), routing protocols (BGP, OSPF, EIGRP, RIP), switching, wireless networking, cloud platforms, data center technologies, and IT certifications. Whether you’re prepping for a technical interview, troubleshooting a real-world network issue, or mapping out your next certification, our content is built to get you real answers fast.
Why We Started This
Networking and IT interviews can be intimidating — vendor-specific jargon, rapidly evolving protocols, and technical depth that’s hard to find neatly explained in one place. We set out to close that gap by creating clear, practical, and interview-ready content written by people who’ve actually worked with this technology in the field.
Who We Are
Network Interview is run by AAR Technosolutions, a team of networking and security professionals with hands-on experience across enterprise infrastructure, firewalls, cloud platforms, and IT operations. We combine real-world troubleshooting experience with a passion for teaching, so our content reflects what actually gets asked — and what actually matters — on the job and in interviews.
