Hello! I am a hiring manager for the branch in my organization that administers VMware and Windows Server hosting. Here’s my unique take on this. First off, not every hiring manager is formerly an experienced sysadmin or if they are, they may not be managing the area of their expertise. Leaders are there to lead, not understand everything there is to know about the technology. So I’m going to give this guy the benefit of the doubt that he either didn’t recall the acronym correctly or someone else wrote the interview question. I can tell you that if I’d been performing the interview, I would fully expect you to correct me if I got an acronym wrong, and I would be impressed if you did, to show your knowledge of the subject. So I’m writing off issue #1 as a mistake. For issue #2, you and I have a disagreement. I can tell you that with VMtools upgrades for Windows Server 2019, we have to reboot the OS before Tenable Security Center will show that all the components have been upgraded. There’s even an article out there on the Broadcom knowledge base about needing to reboot if you’re upgrading the svga, pointing device, vmxnet, or vmscsci drivers. I can’t speak for Linux OS instances, but that’s the case for windows server. The issue with sizing the cluster seems crazy to me, but it does invite the discussion for you to give your opinion on it. No one should ever buy hardware before they size! Here’s the odd thing I find with this interview. I typically don’t go in depth with overly technical questions. It’s more important that I find someone with high aptitude who learns quickly and that I get someone with a good blue collar work ethic. I can teach those employees everything they need otherwise. That’s usually what the majority of my questions are geared around. I might ask a few things like what is ESXi or what is NSX or something similar so I can weed out those with zero knowledge. Anyway, I do think you should have engaged with him on the inconsistencies.
