I applied through college or university. The process took 3 weeks. I interviewed at KPMG (Seattle, WA) in Feb 2013
Interview
Initially applied through on-campus recruiting and participated in a one-on-one interview at my school. Afterwards I was invited to a four-hour office visit, which consisted of a brief company introduction, 2 half-hour interviews, and a 2-hour lunch with their associates. I received the offer within 2 hours of completing the second interview. Everyone was very friendly, and the experience was enjoyable.
All the questions in the three interviews were entirely behavioral and often the conversation was rather casual.
I applied through an employee referral. I interviewed at KPMG (Singapour)
Interview
After submitting my CV, there was a virtual interview and they asked a market sizing question + why I wanted to join the specific department. They also asked about stuff in my CV and it was overall pretty manageable, they don't expect you to know much as an intern.
It was an hour long with 2 hiring manager and HR. Whole process was like one round to offer. This spanned around 2 weeks in total from HR reach out to offer letter.
My interview process went smoothly and required little to no preparation. The questions were all general in nature and were just an overview of my resume. Very low stress interview process.
