The level of difficulty is subjective and varies from person to person. IIM Shillong used to conduct a case-study-based GD. This is unique as very few top B-Schools have case-study-based GD.
Due to the Covid-19 pandemic, IIM Shillong is taking online interviews. One of my friends had her interview last year. The group discussion round didn’t happen due to the pandemic.
There were two panelists present for the interview. They asked her questions regarding her work experience, her academics, her hobbies, etc. My friend has an average profile and she couldn’t answer a few questions during the interview as well. Despite these factors, she was able to convert the call.
IIM Shillong's selection process is different because it is one of the few top colleges which conducts a case-based GD as part of the admission process. There are a number of factors involved in determining the level of difficulty of the question. It is a highly subjective matter.

I hope that now you will get a pretty glance of what actually happens in the GD and PI round.
