I can't really emphasize this enough. Building a brand on the Internet, or even in private, is just the first step in finding your next job. It's an enhanced, modern resume, that encompasses more than just the couple pages you put together to send someone.
I've had many people get upset and feel that building a brand somehow means you shortcut the interview process. That's not true at all. A well built and impressive brand is what gets you the interview, what makes you stand out and what attracts potential employers.
The rest is up to you. You need to still interview well, show off your skills, and present a professional image to those you meet.
