As an intern, you really are doing basically the same level of work as an associate. The work you do is incredibly crucial because it actually goes into the the audit process and the final financial statements as well. When you look up PwC's mission statement it states: "PwC's purpose is to build trust in society and solve important problems." It's honestly great because I never knew much about auditing until my internship but for the big picture, it really is all about problem solving and solving a puzzle. We as auditors have a mission to be truthful and honest and make sure all of the work we are doing is our utmost valuable and honest work.
