BCG came on campus. Resume got selected through the pool. Interview scheduled within two weeks of application. Two rounds. First one was on campus. Two 30 minutes interview with 5-7 minutes of behavioral then a case study. Both interviews lasted more than 45 minutes. Second round at the office. Three 30 minutes talk scheduled. This time emphasis more on fit but still a case study involved. Met with few other members at the office as well. Impression: Super cool bunch of people. Very impressed. I like them better than McKinsey or Bain. Top notch firm...! Take an offer if you get it.
