So applicants are being sorted by browser? How does that indicate adaptability? So if they use Netscape are they too old or too stubborn or too niche for the job? I use Chrome at work and another browser at home, does that mean I get moved to the top of the application list?

I would think some more interesting data points would be what OS were they on or how quickly and accurately they filled out the application or if their resume rambles on with no substance or if they haphazardly used buzz words or look for signs that they didn't create their own resume.

That's ridiculous and doesn't suggest anything other than that's their preferred browser. That's just data to be collected for statistics and shouldn't even be relevant. I'm interviewing the person, not their data, their data could influence if they get an interview if there's actually something interesting in the data, but the browser just seems very odd thing to focus on.

It's worse than you think, AI did the screening interview. I would have run from this company, if they're willing to use AI to conduct an interview then they are going to treat you like crap if they hire you. They basically just let you know that you weren't even worth interacting with by a human. Screw that place.
