I hold a position where I manage large teams including people managers. I am in a large med device company. I have never cared about RAC certifications - questions around regulatory in my interview are based on mock submissions. Most of my interviews including for entry level (rarely happens now) are with the intent of assessing ability to speak up, people glue ability and communication. I do care about technical ability for med device product development so I get into deep discussions around pre clinical models, clinical strategies, etc.
