Blizzard Entertainment User Experience Design interview questions

Speak about the portfolio, I think it will be helpful to talk more and do not leave the gap time, they want to hear how do you work on a project, any detailed information and steps.

First, I have always admired the work that comes out of Blizzard. I think StarCraft is a great game and I've enjoyed every release. The interview process went fairly well until I was asked to take a test. I was told to complete three assignments in roughly 8 hours of my time. The test pertained to a real product and its different sections/features. The test requested that I provide a critique, revisions and wires. Since when did it become the norm to ask highly qualified individuals with over 10 years of experience to take a test (provide free work)? I'm not trying to burn bridges but this is a bit insulting. This is why designers have portfolios. Past work and experience should be sufficient. Also, I was told during the interview that they received a lot of requests for this position. The interview would require a trip to their office in Irvine, CA if selected based off the results of the test. This sounds like a contest to win a free trip or something. Sorry but there are plenty of employers in the world who do not ask for lengthy tests and pay a lot more. I'm very disappointed with this process. I was hoping for something more professional. You let me down Blizzard. This is just silliness...
