Extremely unprofessional recruiter. They reached out to me and set up a phone call, so I looked over their website and "paper" on arXiv to prepare. During the phone call, they made claims like being able to reconstruct an entire 3D scene from a single monocular RGB smartphone photo. I was skeptical about this, so I asked them how it's possible outside of very constrained settings. They proceeded to get so angry that I could hear them seething on the other end, go on a rant about how people from Facebook work for them, accuse me of trying to rip off their IP, and then hung up. The other reviews and the extremity of his response makes me think that this was not the first time. I would be very wary of this company because their claims are scientifically impossible and their recruiter is hostile towards academia.
