Interview a nurse who's over 50 and she'll proudly tell you about her experiences, her amazing love for nursing and her pets. On the job, her pace is slow but steady. She brings in potluck desserts and shows off pictures of her grandkids and her new kitten. But she shows up on time, rarely calls in sick and loves her patients. Interview a 20-something nurse and she gets right down to business: What are the hours, pay rate, expectation of overtime and vacation? On the job, she's on a seemingly flexible schedule, but she's super efficient. She carries a cell phone and checks her e-mail during breaks or lunch.
