It will not be wrong to claim that Chartered Accountants life is usually full of challenges which certainly call for enormous courage and leadership skills. Chartered Accountancy is financially cheaper compared to other streams. It is thus open for students of various backgrounds. A lot of CA students have not had privileged education, such as students from government schools or smaller towns etc, or students who have studied in Hindi but appear for the exams in English. For these candidates, CA course is relatively tough.
Consequently, it becomes a challenge for such students to survive the mainstream competition. Of course, one can argue that the flip side is equally true, since the general candidates in other courses have to compete for a smaller number of positions (due to reservations). However, the low pass percentages must be considered in light of this fact.

There are no set correct answers to these questions. Please understand that the interviewers are veterans in interviewing and a not-so-genuine answer can be easily identified by them. Hence, the key lies in introspecting about your life and coming up with your life story that inspired you to do MBA. That would get you the answer to why MBA. Coming to short term goal and long term goal, short term goal can be to successfully graduating from top IIMs and long term can be to gain expertise in your favorite specialization (do your homework beforehand). Mentioning long term goal to be CEO/MD of any company is not recommended as one can't be that specific within a given timeline and hence, can lead to backlash.
