How do I do well in an interview at Blizzard Entertainment?

Be yourself, demonstrate knowledge and enthusiasm. Most importantly, demonstrate to iterate on design ideas with interviewers, even if you don't know the problem space well, we're trying to get a feel for how to work with you, and your ability to adapt and pick up new ideas, not a comprehensive analysis of existing skills.

Be qualified. Show your enthusiasm. Don't trash-talk former employers. Be respectful of your interviewers, even if they will be your subordinates. Don't panic or rush your answers. Be willing to say "I don't know; I'd have to do some research/thinking." Do not lie.

Use buzz words
