Me: "What am I doing, I don't even deserve an interview for this position, I'm in way over my head. This was my graduate school work but I don't even know what this term MEANS."
Also me: Wow, I just researched an unfamiliar groundwater flow term that I never heard of because it was coined in 2008, a year after I graduated graduate school. Turns out the term describes a concept I developed and presented at a conference in 2005, two years before I graduated.
