Can I attach various supporting documents (my portfolio, letters of reference, certificates, etc.) to my rsum and cover letter?

No = this is not yet available. If you are called for interview, you may be asked to bring any relevant supporting documents with you. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
