The questions in an IIM Indore IPM interview are mostly about academics. They are focused on your personal introduction. That is, your hobbies and interests are well taken into account and questions will be asked right on that to check the depth of your 'desired field'.
They inquire about your favorite subjects and pose questions about them. They want to know why you want to take the course, what your future plans are, your strengths and weaknesses, and your knowledge of current events. They also assess your general knowledge and mental alertness. Though the questions are simple, you will be bombarded with them in order to put you under pressure.
If they believe you are well-versed in your subjects, they will dig deeper and only leave you if you are exhausted. If you succeed in all of this, you will undoubtedly find yourself inside the circular column of IIM Indore. The IPM interview is one-of-a-kind, personifying the course itself. It is both difficult and simple at the same time.

In the later process, you will be asked some common questions regarding your family, your hometown, and other personal questions. Some questions about GK and other current affairs.
To sum it up, be prepared for the following questions:
Be calm and composed, don't be worried if they counter-question you and answer to the point.
