WCA - Questions?

Morning,

I have just had a text to say I have a telephone assessment for WCA in a few days time, suppose I will receive the letter shortly. I have never had an assessment before and I sent in over 300 pages worth of medical reports with the questionnaire (I had to pay for parcel postage). So I am not sure what they are going to ask that isn’t already covered by my medical reports & the questionnaire.

Can anyone share some light into the questions that are asked?

Thank you!
