Jason, you have a good point... I think that if you want to be HAPPY at a job you should try as much as possible to be yourself when you are interviewing with potential future co-workers. But that said, there are also nuances of the interviewing process that you can learn and then if you want you can choose to use them during an interview. The point isn't to try and get an offer from every company you interview with, since you can only work at once company anyhow. But it's an interesting challenge for hackers to try and hack the system and figure out a way for every company to want to hire them. But it's hard to do that without data.

I think that a lot of the frustration is coming from hackers who were rejected and find that they are left without any additional data to understand what that did or did not do that led to the rejection. Through recruiters you can sometimes hear a hint of why the rejection came, but if you work directly with a company they usually don't say anything except for "we liked you but ______"
