Earlier quoted context omitted.
I absolutely did review the interview, that was the whole point. I just wasn't willing to risk sending a potential candidate through a pipeline I myself hadn't gone through. I'm happy I caught the problems in advance myself, rather than subjecting someone I potentially wanted to hire to a useless interview. I do want to stress the useless part here too- even with the notes of how the interview went I wouldn't be able…
In summary, the beginning of a brand new business relationship, you demoed a single, first version of your custom purchase, you understood that it needed tuning, and then proceeded to immediately cut them without providing further direction. (EDIT: Note that I previously contracted with Karat and feel loyalty to them, but have no formal association or stake in them, nor do I represent them.)
What a contrast this is.
