This stupid insistence on ignoring the background and experience of interviewees and instead rank them based on how fast they can write code on a whiteboard is the reason why 1) google can't polish a product to save their lives and 2) every time I look at the code they produce, especially small projects, I cringe with the lack of mantainability, header standardization or design coherence. Keep thinking the best people to hire are the ones that can spout basic cs theory at a moments notice on a whiteboard and nothing will change.
