So, I don't study for interviews because I practice the fundamentals all the time by writing code at varying degrees of complexity. For instance, a silly side project of mine has me writing my own UIs with canvas. Is this a good idea? Well.... The core challenge is there is the job of understanding the machine and the science, but then there is the task of building products for humans. We only have a good sense of how to measure one and not the other. The frustration that I have is that knowing the machine and the science is like... less than 5% of the job (and that's being generous). Fortunately, I made a good career in infrastructure where instead of 5% it is more like... 25%... as the architect.
