I applied through a recruiter. The process took 2 days. I interviewed at Neustar (Santa Clara, CA) in Jun 2013
Interview
VP called me. Chatted on the phone (he was remote) for an hour. Then next day I spoke to the CTO. That was pretty much it. After that I got a call from the recruiter who haggled with me for every dollar and every unit of stock pretty much. But we worked something out and then I got an offer.

Question 1
Nothing was particularly difficult. The hiring manager asked about my management style etc but no technical questions per say.
