To be honest, I don't know. I don't handle the resource management around here.

But you can always send your resume, a cover letter, and some example art/code/story you've created. See the
Larian jobs page for more info. However, this page is for fulltime job applicants, so I don't know what the requirements are for interns. Lynn might tell you more, when she reads this thread.
Oh, and by the way, luck has nothing to do with it. Self-confidence, perseverance, and passion are the key-words here.
