Very well put - participating in the prep industry is a completely rational decision. Context: I work at a FAANG Interviews and hiring at big companies aren’t perfect, but they never will be. Any type of evaluation or test will at best be a proxy for the thing you want to ultimately measure: true performance in the role being interviewed for. I don’t think it’s any company’s place to discourage the interview prep industry. Those who are most determined will seek out resources to increase their chances of interview success. The big downside to the prep industry is that, wherever the cost is high, it lead to greater inequality. Not everyone can effort practise interviews and paid online courses. One positive step I have seen recruiters at Apple, Facebook, and my own employer do is to share free 3rd party resources to help with interview prep. Candidates may not be aware that there are free, high quality sources. These being unofficial endorsed by recruiters helps candidates avoid some of the scammier sites.
