A perfect job interview could be defined as an interview for which the best study technique is to become a better choice for the role. Studying skills that would not directly contribute to job performance would not change the result of a perfect job interview in any way.
In that sense, it's probably a good indicator for Google that the interview advice includes "practice writing code", "make it a habit to validate input", and "learn about data structures", and it's probably a bad indicator for Google that the advice includes "practice writing syntactically correct code on a whiteboard" and "practice solving problems with a 30 minute timer."
