I think a lot of the confusion about how hiring is done or should be done stems from not clearly identifying a goal. For a company on the sale of Google a generalized process makes sense and they have, implicitly, data to back this up. But for everyone else there's just too much subjectivity to have in place a canonical job process. Not to mention the impracticality of using, say, the secretary problem. Having said that, using CTCI or some other book for example to source questions from can be the proxy for problem solving if an interviewer can frame the problem in the form of steps that one needs to flesh out a solution. In that context not having someone google for information makes complete sense and its really easy to use as a filter.
