Kenexa 'Prove It!' microsoft assessment tests

[DanX5]

The mrs has an interview where she has been told that there will be an IT assessment and a colleague says that the company use the Kenexa 'Prove It!' system.

Only a basic part-time clerical / admin position but the Mrs is now bricking it. Anyone done one of these so I can let her know what she is in for? Any practice tests available?

Grateful for any help from PH!
