There are many reasons for doing this: 1) Changing from Via's culture to Intel's culture can be a huge shock. 2) From outside, you cannot tell who is there and what they do. This allows more inspection. Not necessarily for selecting between people but to see how they fit. 3) If a team is working well, you don't want to disrupt that. For example, there might be something critical someone does and if you don't get them, that has to be picked up by someone else and while this transition is happening, there can be a dramatic slow down. 4) It eliminates the guessing game of "who else is looking" or "if they don't go, then, I won't go". 5) Via seems pretty scrappy and they probably have some great approaches that have been lost. I can't find it now but someone recently (DanLuu?) wrote about their experiences at Via and it provided insight into their culture.
