Well, most likely you will be asked questions about:

1. General Knowledge
2. Your main subject
3. Your previous job and experience
4. Intelligence questions (Kinda trick questions, so pay attention to those as your intelligence and situational awareness and response will be checked, try some GRE or GMAT book section about intelligence questions).

Be confident (at the same time dont exaggarate yourself), and be normal.

wese btw interviews i think will take time to be held, so you have plenty of time.
