Yes, the only people/entities who benefit from this type of interview process are the interviewers themselves - They make the interview process needlessly complicated and pointless and then they sell books giving people specific instructions on how to pass those interviews. They create the problem and then they sell the solution as a book or as an online self-help service. All the interview questions do is demonstrate that you've bought the right books and spent hundreds of hours practising pointless coding problems because you have nothing better to do with your time. Maybe big companies are only interested in hiring sheep-like engineers who have no side projects to maintain and no sense of pragmatism... But then why do such companies (e.g. Google) spend hundreds of millions of dollars each year on acquiring startups full of ambitious and pragmatic (wolf-like) people (people who probably would not pass the technical tests). With that strategy, over time, big companies just end up with a few pragmatic wolves at the top and a large number of sheep at the bottom. It's not natural and they're missing out on more balanced candidates who are neither sheep nor wolf but are excellent engineers nonetheless.
