After a recruiting presentation at the university, there was an initial test (GMAT-based). Those who got approved were scheduled two interviews with Project Leaders. The last round was composed of two interviews with Partners or Principals, mostly with Partners.
The office is extremely customized and beautiful. As I have been interviewed with all major consulting companies, I can tell that there was a very friendly, relaxed environment, in which the interviewers sincerely wanted to know you better, both from a business and form a personal point of view.
In hindsight, I could see that several points mentioned in the recruiting presentation (such as respect for the employees and informal culture) were definitely true. I did not have similar experiences in the rival firms.
