I have seen this site and indeed found some valuable info, but I needed to know in more details what kind of subjects have the candidates picked for their presentations.
You can seriously pick just about any topic.
The point there is to get the interviewer interested into what you're talking about.
However, you should use it as an opportunity to kick-start your "Why MBA ? Why HEC ?" conversation.
Good point. Another thing to remember is that the panel may ask you quesions all out of order and intimidate you. Just keep your cool though. Part of leadership is to be able to show resilience to adversity. There really is no rule to an interview, so don't go looking for a formula. But yes, the standard questions you should get down are Why MBA? What are your strengths and weaknesses? Why HEC? What other schools did you apply for? What do you want to do post-MBA?
Whether it's a 1 man panel or a 3 man panel, all other questions will be tailored to your application and your presentation. So have someone look at your file and go through your presentation.
Ultimately, don't over-prepare, because you need to have the mental flexibility for any unexpected questions that come your way. Just remember that you need to be able to phrase your answers in the most positive light.
