First time writing a letter of recomendation. Never saw one about me. In this case I'm writing a letter for a PhD fellowship for an applicant who has not been my student.
I know this student personally, but we worked together only while writing the proposal.
As the title says, in this particular circumstance (if it matters), should the letter focus entirely on the student, or should I also talk about my research interests and how the student fits within them?
