I would imagine there might be cultural differences - in the US it is not unusual to start college without having a major decided whereas in Europe you start right in to your major/certificate program. I don't know how the system works in Turkey.
DD had to provide her CV with all honors/certificates when she applied for her scholarship. If you did not have to provide these yet, I would put together a CV and have the supporting certificates (copies, preferrably) ready.
Some of the questions DD was asked related to her essay topic. Others to her potential contributions to the school (how will you benefit university life here), what she hopes to get out of her 4 year experience (exposure to diversity, learning collaboration, exposure to new ideas), and a "think on your feet" kind of question (if you could have lunch with 2 famous people living or dead, who and why?). These are pretty standard questions in the US, where you cannot be asked about politics, religion, sexual preference, age, etc.
