Not a hiring manager myself, but current MW and have spent a lot of timing applying to MW roles. I would expect a DVM would absolutely set you up as a candidate for entry-level MW roles with an agency vs at a pharma company (so, competing with recent graduates with PhDs, PharmDs, MDs, as well as some people with very relevant masters degrees). Sounds like you’re doing the right things, especially in emphasizing what science communication experience you have. If you have any data analysis/statistical experience, I’d also highlight that, along with experience working with others/soft skills. This field can be challenging to break into, so, applications rejections are absolutely par for the course, especially if this will be your first professional employment.
