Yes. I ran into that with some of my applications as well. I know that in the Coast Guard there was a requirement for marine radio communications. I had advanced comms in the military but that didn't really apply.
For most of the credentials that I ran into, they were on technical jobs. What I raised with the hiring manager is that if these are simple courses, why can't I do the course once I'm in the job? How do the people in the public service get these credentials in the first place? There's no school out there that gives you a radio operator certificate or a rigid hull inflatable operations course, right? Just train me to do it and I'll do it.
