I applied through a recruiter. The process took 6 months. I interviewed at BCG Platinion (New York, NY) in Nov 2017
Interview
There is no other way to describe this than slow and painful. Once you get an interview, there are weeks of silence. This is followed by a hurried next interview. A required trip to New York office to meet face-to-face. All others are done via video. In total, 6 months from first interview to start date.
Interview questions [1]
Question 1
Typical background questions. Then there will be one case study where the interviewer will ask a question concerning a current problem they are facing and get your thoughts on it.
