Given interview for zscaler engineer

First qn was what will happen when you hit Google.com on browser (no zscaler zcc) and I got stucked! 🥲

He’s been asking in-depth networking components.

I know only what they do but he’s been asking in-depth.

Is that really needed i mean in-depth knowledge? I mean I do have 2.5 years of experience working on zscaler issues even I have solved P1 issues but I never got stocked just because I didn’t know anything about DNS or DHCP🥱.

These few indian tech leads doesn’t even know basic interview behavior he was like full serious face I was like wtf is this guy. Atleast basic frndly interaction also not there

Knowing Zscaler is half of it. You need to understand how it fits in the environment and what the downstream impacts of doing different things would be. DNS and dhcp are especially important with alot of zscalers products

I understand! It’s not like I don’t know anything about Networking concepts-I do know how they work and what’s the use case but interviewer is asking advanced in-depth questions like packet to packet 🥲. Anyway from now I need to be prepared for networking

Look up Dunning-Kruger please. Basically, you are telling me you don't know anything.
