A friend and I are arguing about the number of pages needed for a coverletter, to apply to postdoc in electro-engineering.
Usually, the postdoc offer (what I called a job offer) says up to 3 pages.
My friend fills the 3 pages for the coverletter.
To me, he should stick to one page , presenting himself, his work and why he is the most qualified for this position like any regular jobs actually.
I feel I'm right but as I do not have much experiences applying to postdocs, I cannot validate my claim.
Any insights are more than welcomed.
