I sent my resume to a partner that was at a campus event. I then received a call from HR, we had a pretty brief and laid back conversation. They then set up an office interview. The office interview consisted of 4 1-on-1 interviews. The first two were with Audit Managers and the second two were with Audit Shareholders. All of the interviewers run down your resume with you and ask you questions about your experiences. I would recommend bringing a copy of your resume with you so you don't waste your time craning your neck trying to predict what they are going to ask you about next. This part is pretty easy if you are prepared, be ready to elaborate. The second part of each interview was just a conversation be. They want to make sure you're a reasonable person that they think would fit in with the current employees. Sell your self. They are looking for people who are hard working and easy going. Which is basically what every employer is looking for I would imagine. Side note: All of the shareholders and managers seemed to be Steelers fans.
