I agree and disagree. I agree that there's something out of kilter here: Items 2 and 3 are possible breaches of the employee's non disclosure agreement with Google. And "poaching" is the widely used term for this kind of activity.

On the other hand I see nothing fundamentally wrong with getting a job and a salary bump without an interview, based on a personal recommendation, if it's information that can be freely disclosed. I got my first job out of school with only a cursory interview.
