Recently, I posted the GDC 2012: Blizzard Entertainment Speakers Schedule.
A few days ago, the info was not available, but I just got confirmation via twitter the Blizzard Careers Team will be at the GDC Career Pavilion, Booth #1408.
If you are a GDC 2012 attendee, walk by their booth to say hi, bring your resume, cover letter and your portfolio or demo reel.
Samwise Didier and Chris Metzen got a job with Blizzard in a similar fashion. So can you.
