I've interviewed 3k people with Karat as a professional interviewer, and several hundred more as a hiring manager. The very few times I received direct emails from candidates attempting to circumvent the normal process were met with unequivocally negative reactions. First, I find the Internet sleuthing they'd undergo to find my email address a bit creepy – for example, Karat would only show the first name and profile pic for your interviewer. But more importantly, the sheer audacity to go for such a stunt would firmly anchor them in the box of people I'd never want to work with. I'd still be polite and professional to a fault, of course, but I'd never seriously consider them past that point.
But in bad times where "the normal process" can't even let you have a human look at your resume, it's different. "circumventing" is at worst a simple act of rebellion to annoy people who can change their process. It's a best a chance to actually get the response that isn't even granted with a form rejection these days.
