1. It is okay to say ‘I don't know' in an interview’ Instead of answering a question without any knowledge about the topic (read bluffing). Be humble and state that you are not aware of the facts. 

2. Here’s the classic opening question in a PI – ‘Tell me something about yourself’.

Answer to this question can make or break the interview. Typically, one should talk very briefly about family, education, career goals, hobbies and interests. Do not talk a lot about the past. Briefly refer to past education, life journey and future plans. 

3. Another common question is, ‘Why do you want to do an MBA?’

Answer such questions keeping in mind the holistic development you’ll get during MBA and acquisition of skills for life long success in personal and domestic space. Remember, post an MBA, one lands a job in corporate where there’s a rapid career growth along with high monetary returns. But then, management as career, is also a challenging profession. 

4. The third common interview question is – ‘Where do you see yourself five years from now?While answering this, focus on skills development, increased responsibility while highlighting on your goals as achievement. But do not say I want to become VP or General Manager or similar stuff.

hope it helps 

Thnak you!
