Funny thing is, its such a broad question but if candidates ask questions to narrow the scenario down they can make it easier for themselves and for what you’re aiming for as well. You did say 2k-3k users already but what about budget, wireless only for users, is the company fast growing, leveraging cloud or not, SD-WAN if theres critical internal apps, multiple ISP lines, DIA links? That really makes a good network engineer standout

Specific interview questions suck imo. I’m going to ask about your resume then try to blend it in with what we’re looking for in a candidate. You can tell who’s exp and who isnt

hold on. most modern enterprise or isp class devices can do multiple roles at single device. so wan-fw-core can be single devices. and actually should be - less points of failure. so as wireless controllers can do guest / corp wlan, so you don't have to have extra fw in between. your scheme can actually be kind of a 1st picture but with redundant isp-core-fw device 🤗

we only have a wlan controller so far we still need WiFi access points right and they would be connected to the access layer

I would start off by asking what the budget is and then get technical 😁

Way back when, hiring grad roles… The standout applicant had been properly taught networking, rather than taking every CCXYZ there was. He could talk about the entire user journey to get to www.google.com from ARP, DHCP, default route, DNS, firewall, internet connection… That should have been the bare minimum, but ended up distinguishing between “I did certs to get a job” vs “I wanted to understand or was taught how things work from the ground up”.

You need some encryption devices too between the DCs, remote and Distribution. Vpn server?

what`s about IPAM and DNS? No in a large Enterprise DNS in AD ist Not the solution. 1 you should seperate Services to different Systems, 2. the DNS should not run with higher permissions. An AD integrated DNS run`s as SYSTEM.

Just something I hope your viewers don’t get confused with. The traditional WAN and Internet architectures are not the same. You’d likely need a WAN edge and an Internet edge with internal and external firewalls to create a DMZ for external facing applications.

And here I go with my own tablet so I could try to explain the same thing. So I can sound more confident if this question ever comes up. 👏

Oh! Okay lemme try then! Okay first we're going to need a data center. Everything that our clients talk back to. We're going to need a remote backup site for redundancy. We're going to need our CERs or possibly PERs for the actual sites themselves, however many we have. We'll need firewalls, switches, floor lines ran and WAPs for the devices that are going to be attached. and this probably isn't what you're looking for but we'll also need a crew to man each one, enough people to actually keep this entirprise network up and running including engineers that can remotely monitor and log on as well as engineers onsite to troubleshoot physical issues at each of our sites. let's see how close I was to what you were looking for.

I like to ask someone to describe end to end what happens when you load Google.com in a web browser including all associated protocols they know about. Just to describe it end to end to the best of their ability. I like to see if they call out arp, DNS, route lookup and the way the packet gets out, then back.

No redundant core and firewall?
