By far the most exhaustive selection process of any job I've applied for. You submit a package that goes before a board. Includes a physical, an essay, an application, and various and sundry other bits of paperwork. You interview with a Chief Nurse. College transcripts need to be submitted as well as letters of recommendation (this is one job where you will be judged based on your GPA). And then you wait awhile to see if you're selected. You have to do well in every area. You can't just charm the interviewer and bank on getting the job. The people who judge your package are completely separate from the person who interviews you, and the interview counts for only a small part of your package. In short, you have to look good on paper because the board who selects or rejects you will never see your face.
