I applied through campus recruitment, graduate program with a 3.6 GPA. Prior to your first round interview, there will be a reception. This is pretty casual, use the opportunity to ask questions and introduce yourself to the recruiter and Associates/Partners as they may interview you the next day. 1st round is a simple behavioral interview, know why you want to work for Pwc, explain your background, and ask questions. Most importantly be excited and show you are eager to learn and have something to add to the firm. Final round interviews in NYC are a superday, two 30 min behavioral and one case interview. You will most likely meet with a Manager, Senior Associate, and finally a Partner. You're given the case two days in advance so you can prepare, and upon arrival are given 45 min to prepare a presentation on hard copies of powerpoint slides, and answer additional questions given to you upon arrival- this is nothing to be worried about! Some people who prepped for months doing case studies did not get an offer- I had no prior case interview experience except from a class the previous fall semester. I read some of Case and Point and watched Victor Cheng's youtube videos. You will simply present your slides to a Manager or Senior Assoc. I suggest using the STAR method for all behavioral questions. There will be A LOT of time for you to ask questions, so DO YOUR RESEARCH!! And- do not forget to send thank you emails to EVERYONE you met with before the end of the day. I had my final round interview on a Friday, the Partner called me on a Saturday to offer me the position.
