I remember John Washam's original blog post that followed his preparations for taking a Google SW interview. At the time, I felt he way over-prepared and wasted time on things that weren't directly relevant to the actual interview. Looking at his new study plan, it looks like he's learned from his original undertaking and created an exhaustive list of things to know for a FAANG interview. I do think he skipped over the behavioral interview preparations which can be extremely important for certain companies.
