Project Related Interview Question

Lakhi kant RoyI have made a project called "e-shopping mall management" in my final year which is made using j2ee. I want to know what kind of questions should i prepare before appearing for an interview.

The most obvious questions, without looking at the code would be:

1. Why did you choose this project?
2. What does your project do?
3. How is your project from different regular e-commerce websites?
4. Why did you pick up J2EE and not any other platform?
5. Give us/me an overview of the code.

PS: It's difficult to really ask questions based on only project title. I'm sure our fellow engineers can come up with more questions after knowing further details.

Thanks.
