Zerion Software interview questions

The interview was supposed to be a non-biased interview. The problem is that it asks you very specific demo questions and has you record a video that they evaluate before passing you on to Zerion. If you are going to have someone record a video, let them know that ahead of time. Also, if you require in depth research on your company and the markets it serves, why not give the candidate a heads up on what that question will be? Especially in a screening process that doesn't involve another person but the candidate.

I submitted my resume, did some homework including submitting a video clip of why I want to work there and what I expect from Zerion. They kept pestering me to submit a video interview after already going through the interview process
