Network engineering grad, bombed my first interview on OSI layers, never touched a real server where do I start?
Be honest with me. Degree says Network Engineering,i graduated from china. But coursework was mostly general CS + IoT. Not to blame my school i should have known this from the start but i thought my school was teaching me something and it should be from my major. No real hands-on networking, no Cisco labs. Degree itself is on hold pending a language requirement too. Had my first interview recently. They asked if I'd ever worked in a lab or touched a server — hadn't. Then asked if I knew the 7 OSI layers. I didn't. Blanked completely, told them honestly I'd never heard of it. Failed. And i have a job interview tomorrow. Now self-studying CCNA (NetworkChuck), doing Packet Tracer labs on my own (VLANs, basic routing). Applying to banks, a couple ISPs, few other IT shops. Need a job soon, so I need to prioritize right, not study everything. Questions: Beyond OSI layers (already drilling this hard now), what other "should just know this cold" basics get asked at entry-level interviews that I should assume I'm missing? No real server/lab experience — is there a way to fake competence here short of just saying "no," or should I be upfront and pivot to what I have done (Packet Tracer)? How fast can someone realistically go from "didn't know OSI layers" to "interview-ready" if they grind daily?
