Man, is this a new trend maybe caused by COVID or maybe I just haven't been outside the Government (Military) space and its the norm, although I interviewed for FAA and a I.C.E/D.H.S contractors recently too and they did the same.
But you get the HR guy or Project Manager on the call rightfully so and also here's Tom, ****, and Harry they're in the position you're applying for and they're going to ask you some questions.
I see the value it could potentially have if it was this is what we do everyday, what do you know about this whats your skill level, but they all devolve into the incumbents trying to prove they're smarter than you. You can imagine how smug stereotypical IT nerd types can be too.
So they'll ask a bunch of definition type questions (90% of which have no relevance to the job, again just trying to make themselves look smarter than you), and the ones I did answer dude is literally like Ok well how bout this then, it's so unnecessary and they insisted on video so I am not sure how good I do with hiding my frustration in my facial expressions. But then you get to the behavioral aspect of the interviews or ask me about how to do tasks related to the job type thing, I ace that part but the wasting time asking me tons of textbook definitions and random things that don't matter I feel like puts me behind the 8 ball. I feel like they're still going to offer me the job though because again when we talked about what they do everyday and demonstrating I can/have done it in my experience I always crush that part. Also got a few personality assessments where there's like 500 adjectives on 2 pages and you have to check the ones that you think describe you. Like wtf is this kindergarten?
Almost all my other interviews with Army/Air Force contractors are literally just them checking boxes, you have a clearance, ok tell me your social so I can check it, security + or other IAT I/II cert, send me that to verify, talk a bit about the job and make sure you're ok and you're good pending you don't do/say anything outrageous to preclude yourself.
