Had a couple technical phone screens with current engineers, and then I was invited for a day of on-site interviews. The phone screens were covering pretty basic technical areas based on my previous experience. The engineer was very pleasant. He asked about FSMO roles in Active Directory, what are the aspects of setting up a VPN connection between two sites, what all happens when www.amazon.com is typed into a browser, and some basic firewall questions. On-site, I met with a couple engineers, and several managers. These were a mix of technical questions (describe how you'd set up a network with three locations, what is a GPO and how is it applied in AD, etc) and soft questions (Tell me about a time when doing things the normal way didn't work, Tell me about a time you came up against a problem you'd never seen before, etc). I thought the process was very thorough, but I never felt like I was being grilled. The people were all great.
