The process took 1 day. I interviewed at Grant Thornton (McLean, VA) in Apr 2011
Interview
We had a pre-interview dinner that went great. The employees were from offices all over the country. They were full of personality and made dinner an extremely pleasant experience. The interview was the next day and only lasted for about 20 minutes. The only question asked was, "Name one your greatest accomplishments."
I applied through university. I interviewed at Grant Thornton
Interview
2 directors asked about general interview questions, including tell me about yourself, strengths and weakness, any prior accounting internship experiences. There were no technical questions which were asked in the interview, mostly behavioral and conversational.
Pretty simple. Just two rounds, back to back (30 min) with two different people in the same department. It was all behavorial questions and mainly just concerning my resume. Overall, they were very nice and it was good experience.

2 interviews back to back, one partner, one senior manager. STAR behavior questions. Overall very go with the flow, but must show concrete examples and no technical questions asked .
