PwC infrastructure modeling test

Hi all,

I have a financial modelling test coming up with PwC infrastucture team. I understand this will be an IPP model and will have a day to prepare and send the model back. Any clues and tips on what to expect in terms of level of detail and how I can prepare for this? I have done fair bit of modelling in the past but haven't done so in a year or two so need a bit of brushing up.

Much appreciate your help and advice.

Thanks
