Major part of your preparation is done once you prepare for CAT rest all exams have their own pattern and way of asking questions so we need to just add on some things based on that particular exam like
XAT- Decision making is a new section to deal with
SNAP- Vocabulary and grammar, some add on topics in logical reasoning like clocks, calendars, verbal reasoning etc. IIFT more about calculation and vocabuary again plus the questions are very lengthy in IIFT so get used to extracting the data fast from question
NMAT- Vocabulary and verbal reasoning, 50% of Logical skills section is verbal reasoning
So you just need to make these small modifications for each exam once your core preparation is over.

Preparation Tips:
1- Study Current Affairs daily:
The General Knowledge section is such a vast one that anything can be asked from anywhere. As a result, you cannot predict what the actual syllabus will be. Choose a particular teacher, either offline or online, and study Current Affairs on a regular basis.
2- Prepare business- and economy-related general knowledge questions:
Business and economy-related questions are vital topics in XAT SNAP and IIFT. The XAT SNAP and IIFT GK Questions revolve around topics like business awards and honors, economic policies, logos, changes in the corporate and industrial world, and many more. Students can take help from articles, newspapers, business magazines, and business news channels.
3- Complete Mock Exams and Online GK QuizzesTry to attempt at least 2 mocks once a week for the XAT SNAP and IIFT exams. The number of mocks should increase gradually. Your speed and knowledge will gradually improve as you solve more mocks. Moving on to quizzes, the students are advised to attempt a quiz daily.
4- Try to form multiple questions from a question. While creating their notes on XAT SNAP and IIFT. The students should keep in mind the topic they are studying at the moment and take notes in a way that covers all the questions related to it. In this way, the whole topic will be finished. I hope this will help you.
