Following an application and initial screening via e-mail, a relatively informal proper interview with multiple team members that touched on the role, its responsibilities, and the needs it is meant to fill. At the end, exchanged thanks and said they would be in touch. Then, as other interview reviews have noted here, they ghosted. It was wildly unprofessional. They can't even be bothered to respond to follow-ups. I have never experienced anything like it. And then I ended up here, saw the overwhelmingly negative workplace reviews and it made a little more sense. Anyway, it takes 30 seconds to write a polite email informing someone their application was unsuccessful, something you absolutely ought to do if you spoke to them face to face. Not getting a job is no big deal, it happens all the time, and no hard feelings there. But it's a huge red flag when a company clearly lacks professionalism and manners right down to HR.
