But if they worked ‘real jobs’ in the summer they’d know what to expect, don’t you think? It’s a real character-builder.
Most of them either teach or do research during the summer. Maybe when they were younger they worked in service jobs (fast food, retail, waiting tables, etc) or did internships at companies. However, those are limited experiences. IMHO, it takes about 2 years working as a professional to get the student mindset and habits out of your system.
