That point I get, people may not enjoy prepping for an interview. That's different than asking "Why should I prepare for a job?" If you want the job, you'll put in the effort to prepare, regardless of your feelings on the process. That sacrifice (2 hours a day for a month) is minor in the grand scheme of things. Granted to the OP's point, Google probably isn't worth it. But that's a value decision each candidate has to make for themselves. I'm preparing for my brown belt in Krav Maga. The test is 6 1/2 hour grueling physical exam that includes a comprehensive test of all the material from the previous 4 belts. Not only that, we're the first group eligible to test, so the instructor wants to set the standard with us. Not everyone wants to put themselves through that hell. But those that do will put in the effort to be ready come test time.
