I applied through campus career center. The process took a 2-3 weeks and was very professional. First Round: Over the phone, one case and one behavioral. Both people were very nice and professional, and made sure to make you feel comfortable during the interview. Final Round: In office, 2 cases one behavioral. Everyone in the Chicago office was very welcoming, and tried to relax the candidates who were interviewing. Behavioral was more of a conversation rather than being grilled by classic behavioral questions, and the cases were a bit more qualitative. Not really sure if this is consistent across all interviewers at AT Kearney.

First Round: Two 1 hour long interviews. 30 minutes on CV/fit questions, and 30 minutes on a case study in each interview. Second Round: Written case study task (including excel and powerpoint) and presentation, plus another CV interview
