Help, Nlng Test Format

Hello fellow Nairaland users,
I've just been invited for an aptitude for the position of a Graduate Trainee in NLNG.
Does anyone have any useful information as regardrs the nature of their test for this position?

Meanwhile, the test is coming up on 3rd March, 2007 at UNEC, Enugu.

Kind regards,
Ken.
