I was contacted about a potential game design position and was given a face to face interview. After the interview I was given an art test with four parts (painting two characters, storyboards, a 3D model) with instructions to email them if I had any questions.
After this, communication was sparse if it happened at all, with me having to call multiple times and email multiple times to get answers or feedback of any kind. After a month of being promised that the client wanted to talk to me but never getting back to me, communication stopped.
Six months later they messaged me out of the blue asking if I'd be interested in the same position, and then asked me to immediately answer emails and questions, and then proceeded to not communicate once again. Calling with questions about the interview we had scheduled or for a confirmation ended with them saying to "hold on a moment" before going quiet and eventually hanging up.
