Bain & Company Part-time Assistant interview questions

Found this job via an alumni; Got 2 rounds of phone interviews and they asked me to get onboard asap; Overall a smooth experience, nothing too crazy and difficult; possibly because they want someone onboard quickly

Be invited to a group interview at Beijing. Read a case together with the 8 people group. After ten minutes, we were required to discuss about the case. Then gave out a presentation about the findings. The case was something including market sizing. Actually it happened in 2012 so that I could hardly remember. The presentation was given by only one representative from us. The consultant held the whole interview. After one week, I got the result.
