I found, that at the undergraduate and even graduate level, the Institutions where I received my otherwise not bad education did not disclose what kind of careers you can hope to aim for with their diplomas, or what one needs to do and accomplish (other than getting their diplomas) before one can land "their dream job". This kind of information I got mostly by word of mouth, step by step, and by overhearing professors etc - not through any kind of formal class. But maybe my experience is unique and is due to my Eastern-European background (or even specific to the two Universities I received my education from or the time I was educated at) so I would be interested to hear your experiences regarding "career development courses/classes".
I think this should be taught in class just like pubmed and PMC (and other database) searches, ways of using libraries, searching for grant/fellowships/patents and writing proposals, making yourself "visible" plus other basic skills every researcher needs in biomed and probably other fields as well.
