Video chat code challenge was not. It was to create a spiral loop over a N size matrix. It has no real-world use cases, and doesn't show nearly enough depth of your abilities. I have not once in 10years of coding, ever needed anything even close to this. I self taught myself coding and have worked for Google, CNN, etc. It was a purely computer science question. I think they are missing out on good and diverse talent because they only target CS grads.
