Noc interview questions

Passed the phone interview. Now on to the real thing. They use vbscript and hp service manager. Have no idea about the service manager so gonna review that and watch some tutorials. Can anyone give me an insight into what the interview would be like? Questions usually asked n material I should brush up on.

Also HP Service Manager is horrible, Its HPs Ticket System. My personal opinion on it is that its bloated, slow, and almost useless.
