I did'nt get asked anything too technical when i got the job where i am now (been promoted to network manager since).
1. Mostly scenario based questions on how you would priorotise if two or three problems came up at the same time.
2. Whats the difference between a switch and a hub.
3. Whats the single most ICT related important thing about working in a school environment where exams are done online etc. (Backups)
4. You arrive at a printer which is not working. What steps do you take to find the fault and in which order.
5. A user cant log onto their computer with their password. What steps do you take and in which order to determine the problem.
6. How do/would you deal with users with a limited technical knowledge.
7. How would you feel about doing other jobs like cleaning mice balls, tidying the office etc.
Make sure you ask some questions and show your interested - maybe make some notes at the interview. The only other thing is to show your commited as most people dont stop long in these posts because of the pay etc - esp in Staffordshire
Good luck
