This is a very negative view of what an interview is. Most interviews, however carried out, couild be described as "trying to predict the mind of the person asking the questions" but most interviewers are trying to get a realistic view of the applicant with very little objective information. The bigger the company, the more likely people have "trained" up to try and give themselves an advantage over others. I don't think companies are necessarily looking for people who have dedicated weeks of learning, but that learning can certainly make the applicant look smarter than they might be.
