The process took 2 weeks. I interviewed at Grant Thornton International (Atlanta, GA) in Jan 2008
Interview
I first had a phone interview followed by an on-site interview with multiple members of the audit group as well as senior management. I had a total of four people I met with. We also went with a group to lunch to discuss culture and see how I fit in with the team. An offer was given via the phone and then sent in a package by mail.
I applied through a recruiter. I interviewed at Grant Thornton International (London, England)
Interview
3 rounds which were case study presentation , technical and then Management round. The interviewers were very clear on the questions and make you feel comfortable. Overall interview process was good but they take a long time to decide to give the offer.
