I suspect I've discussed this position with a friend who is currently job-seeking. She hasn't applied because (1) she doesn't have 4 years experience in health science library and (2) she doesn't have sufficient health science coursework. She has more than 4 years experience in reference/instruction with science emphasis and has undergrad degree in microbiology.
OK, this is confusing me. The ad for the job I'm talking about asks for undergraduate or
graduate background or
significant work experience in the biological or health sciences. A major in microbiology certainly fits that description. So, maybe it's a different position you're talking about. <disappointed face>
