Interning anywhere is all about effort and enthusiasm. Do the easy stuff: be punctual, be prepared, be attentive. Then, take it the next step...ask meaning and substantial questions, always be willing to learn more. If you don't have anything to do at a particular moment, ask if there's anything you can help with. If there's nothing, don't sit on your phone or twiddle your thumbs.. go online, use Google or Deloitte's many portals, and learn - complete training, look up industry news/events, or network. Networking is huge in Deloitte - don't be afraid to reach out to people and ask about the work they do and any advice they may have for interns. Deloitte is known for being an open workplace, where people want to help others, especially interns, in any way they can...the only way you don't build relationships in this organization is if you don't try. So, long story short, show up, work hard, ask questions, be proactive, and network. The technical skills will come, or be taught.
