Wow this is a question, first off I wish anyone luck getting a interview with NetApp. You have a very small % of a chance to get into NetApp without a recommendation and if you do kuttos to you! In my department of Marketing NetApp uses a lot of unique tools created internally by the company, so they do not expect you to know them. I would suggest to be passionate to learn and willing to talk to people to learn of all their capabilities. My job title has changed but this is true across the whole marketing organization. Never be afraid to ask questions, curiosity is key.
