For those that have received interview invite, congratulations!!!
Kindly use the debrief section to prepare. However, don't memorize your answers not to sound like a robot. Lol
Get your Whys right (Why MBA, Why Now, Why Kelley)....then for your behavioural questions, get your stories ready. Your stories are not meant to be from your professional life only. Better to mix it. Professional, College days, Volunteering experience, Personal etc.
For example: "Tell me about a time your team member did not participate in given tasks"....here, you can use group assignments from college days to answer this, if you have a scenario.
Wishing you all success.
