There are many odd things about being in an acquisition, not the least of which is having an enormous support system for job searching. It's also wonderful. I have an interview coming up, and I don't want to jinx myself so I won't say much - except that I'm so excited about the position and the company that I've barely slept for several nights.
The resources at Sun are amazing. I got advice from someone in HR about phone interviewing; my mentor gave me in-person interviewing tips and reviewed my resume; a coworker reviewed a relevant open source license with me. I've gotten several offers to be a reference.
I'm hard-pressed to think of another situation where this might occur. It's a little like leaving law school, I guess; except everyone is much better connected, and your professors are looking for jobs too.
