Boston Consulting Group Summer Internship interview questions

standard case + behavior interview. Two rounds, each 45 minutes. The difficulty level is rather normal, but one of the partner was not very nice. The voice input was disrupted by echo but he doesn't seem to care that much. He subtlely pressured the recruitment officer to shift the responsibility on me. Not a very pleasant experience.

The first round was 2 case interviews back to back. Both interviewers were nice and guiding. The second round was the same but the cases were less structured and felt more like conversations rather than a traditional case interview.
