On Jobsblog, Jenna posted about a Microsoft employee that left and came back. Last week, at our Silicon Valley Networking event, two of the hiring managers from the BMO team talked about how they left Microsoft and came back too. Mostly, I think that people tried some dot com stuff and decided they like what they had. We don't have an adversarial relationship with people that leave and try something and want to come back. If they were a great performer, I say welcome!
