I returned to work as a graphic designer after 18 months as a SAHM, then quit 2 years later to pursue graduate school. Unfortunately, that didn't work out and I'm finding it harder to get a new job after the brief stint in grad school than I did after being home with my son (which I've not been disclosing). I'm feeling pretty hopeless about my prospects, so I am trying to update my skill set. I'm overqualified for most of the jobs I'm applying for, but that doesn't matter to me. It clearly matters to these employers. What am I doing wrong?
