Much of your answer to this question will depend on your role - so do some careful research into your chosen department.

In M&A, you might spend much of your time on financial models related to the deals you're working on, while in a trading role you might start out by assisting more senior members of the team before being given the chance to manage a trading book yourself.

Beyond that, it's important to show that you'll be keen to take on responsibilities, but that you also recognise that your first year is about learning the ropes, which usually means include following instructions from others and completing some mundane tasks.
