Possibly make their point of contact an engineer rather than an HR person. There are definitely benefits to this, as you mention, but taken to the extreme (all recruiting is done by engineers), it's a pretty high cost to the company's productivity. Think about it from the other perspective: would you, as an engineer, want to work at a company where a significant portion of your job is recruiting? If you were the CEO, would you rather your engineers focus on recruiting or on engineering?
