"“Our experience has found that most graduates from these programs are not quite prepared for software engineering roles at Google without additional training or previous programming roles in the industry,” said Maggie Johnson, Google’s director of education and university relations, in a statement. “We generally don’t hire from coding schools,” said Robyn Blum, a spokeswoman for Cisco. “Coding schools haven’t been much of a focus for Autodesk,” said Raymond Deplazes, a spokesman."

Bootcampers tend to have roughly the same level of programming skill as someone fresh out of a CS degree course who has brushed up on the tech we use. Additionally, many have backgrounds in other fields (everything from working in a small business to line cook to psychology to sales).
If your company isn't prepared for the mentoring and training needed to deal with junior developers, hiring someone fresh out of a boot camp is a bad idea, especially for someone like Google or Cisco that does a ton of programming at much lower levels than web development and doesn't treat it as a primary focus (where more resources are likely to be spent in mentoring).
