While there are many legitimate criticism of whiteboard-style coding interviews, I have yet to see a convincing alternative that scales well to the size of big companies. Google [1][2], Facebook et al. hire thousands of engineers per year, meaning they conduct at least 10-100k interviews per year. How do you design a process that is consistent, measurable and efficient at that scale?
