If you interview at enough companies you can find one that allows a Gattaca to slip through. Of the subset of companies that allows that some companies let people float without doing any real work for a long time. The longer they coast the more likely they can find a corner to hide in. There is no penalty for them to try this approach. Even if you caught them in a lie the effort to make them pay for their actions means they likely will never be responsible.

One company I worked with checked government issued ids at every stage of the interview process. I'm sure people will find a way around this. This also opens your company to discrimination lawsuits, "everything was going fine in the interview until I turned on the camera, then they didn't hire me."
