This question already has an answer here:
I just graduated from grad school and joined a job at a large software company in the US 3 months ago.
I enjoy reading recent research papers to get ideas and to understand what's going on in the field. Recently I found a great paper that wasn't directly related to what I'm doing, but does apply to work another group in the company is doing.
Since I don't work directly with that group, I sent a quick e-mail to the senior engineer including the paper, saying:
Hi, my name is samarasa. I'm a new software engineer working on project A. When looking at research papers on this sort of work, I came across something that may interest your group.
Instead of being grateful, the senior engineer responded that it wasn't my position to be making suggestions since I was new on the job, and working in a separate group.
Was my behavior out of line? How should I go about repairing any damage I may have caused?
