Apologies if this is posted elsewhere, I'm curious about others' experiences with letters of recommendation for post-doc applications. Most sites I'm looking at say to include three LOR, some specifying including one from dissertation chair and some specifying at least one LOR from internship. I'm curious what others did for an internship specific LOR or that third open LOR - did you ask someone on internship to write it for you? Did you ask someone from a previous clinical experience or from grad school? I'm struggling with who to ask from internship considering I will only have been working there for three months by the time I need to ask one or more people for letters. It just seems really soon and that they would have little to say about me for post-doc apps.
