The process took 6 weeks. I interviewed at IBM in Jun 2010
Interview
- Relatively regimented interview schedule, as would be expected with such a large company
- Standard interview process for a consulting position
--- Phone interview covering background and essentially informational
--- Interview with a Partner covering experience and project work specially related to the position
--- Second interview with a Partner covering experience and also behavioral/fit
--- Interview day (in an IBM office): small group case (team of 3-4, limited time, presentation to "board"), 2-3 interviews with Partners (usually a good sign if the hiring manager interviewed you over the phone and at the Interview day)
