Hi,
Without knowing more about that technology my suggestion is don't go for that interview why because may be they are expecting some what more experience in that platform. So, before conduct interview itself you just intimate to HR if they said ok and that is not a walk in then you can attend that interview. If you are looking SharePoint interview question then search in online there are n no of links available for the same and prepare those questions before that you should have a basic knowledge about that technology.
Hope you get my point...
