I'm applying for a job and on the posting it mentions that cover letter and resume are required and to send cover letter and resume to a specific email.
It's for a programming tutoring position. I previously worked as a programming tutor and developed basic instructional material. I put down on my resume that I did this. I was wondering if it is okay (recommended, or not recommended) to attach a .PDF file (of the instructional material) in the email? I was thinking of writing this in the body of the email: "For your reference, I have attached instructional material which I created while previously tutoring students (which I have talked about on my resume)".
Okay, good idea or bad idea?
