Like all Big4 firms the application and interview process can start a year or more in advance of hiring. After submitting my application the first interview was on campus. After that I interviewed at the office with a couple managers and one of the partners. I received my offer within days of the final interview. The interview was more behavioral based since they want to ensure proper fit with their culture. I believe that this is because at the entry level they just want to ensure that you will be able to have the type of personality that can work on a team and be able to handle the workload. It is important to show that you are interested in the work and the firm itself.
