As one of my friends also has gone through the same situation, I might be able to provide you with some tips that could be useful to you.

• Expect nothing out of the ordinary that will catch you off guard. 
• The interview process is straightforward and very conventional. 
• There's no need to be anxious if you have good reasons for what you've written on your CV and SOP. 
• Be meticulous with your SOP and CV, as most of the questions to be raised would be sourced from what’s written in your CV and SOP. 
• Remember, your desire to do an MBA should be convenient to the panel and they must know exactly why you want to get an MBA degree.

In most cases, case-based GD is offered, therefore XAT decision-making questions can be useful during preparation. If you have any prior work experience, you should expect some questions from that section as well. Hence be prepared in that way to walk through this interview round.
