How to become a Network Engineer
Design, configure and troubleshoot the networks everything else runs on: routing, switching, firewalls, and the labs and scripts that prove you can do it.
Best for
Students who like physical, diagnosable systems and clear right-answers, and who are happy working in NOC or support early to earn depth.
Maybe not for you if
Anyone set on a software-development career. This path leads into infrastructure, and moving across later is possible but not automatic.
The 4 phases
What each phase gets you to. The steps, resources and checkpoint inside each one open with a free account.
Phase 1 - Networking fundamentals
5-7 weeksGoal: Explain, layer by layer, exactly what happens when one machine talks to another, and prove each step with a command.
3 steps · ends in a scored checkpoint (70% to clear) · assumes basic computer literacy
Phase 2 - Routing, switching and a home lab
6-8 weeksGoal: Configure a two-site topology from nothing, then fix it when you break it on purpose.
4 steps · ends in a scored checkpoint (80% to clear)
Phase 3 - Troubleshooting, automation and network security
6-8 weeksGoal: Diagnose from evidence, script the repetitive parts, and lock the network down.
5 steps · ends in a scored checkpoint (70% to clear)
Phase 4 - Certify, clear the process and get hired

What hiring actually looks like here
CCNA is commonly treated as the benchmark entry certification for networking roles in India, and employers typically weigh hands-on lab practice as heavily as the certificate. Common entry titles are Network Support Engineer, NOC Engineer and Implementation Engineer, usually on a shift rota. Expect three filters: a written aptitude round at large employers, a timed subnetting drill, and a long conversation about one fault you personally found and fixed.
