That thing about waiting for the interviewee to send a thank you note before deciding on them is the stupidiest thing. Firstly, it discriminates against autistic people. Secondly, it wastes everyone’s time. Why interview before figuring out whether the victim follows your ridiculous social mores? If you were smart, you could figure that out beforehand in a phone call. Any company that uses this ”technique” should be avoided like the plague in my view.
