Hi,

Hope you are doing great.

The exam structure for GIIS is :

Part A contains MCQ-type questions of English, Mathematics, Logical Reasoning.

Part B contains subjective questions that are essay writing.

And then the final selection depends upon the interview after clearing these two rounds.

So for sample papers, you can use a third-party website by using google search and the previous year's paper is not yet available officially.

Hope this helps.
