A job description is not a job ad. I cannot stress this enough. There is nothing more tiresome than to see an ad like this:

Requirements:

• At least 5 years experience 
• Ability to make swift decisions, work through stressful situations and solve problems quickly 
• Deep knowledge of your area 
• Creativity 
• Ambition 
• etc.

Does this make you want to jump up, tell your boss you're leaving and go work for this company instead? I don't think so. This hardly evokes an emotion, much less the feeling of wanting to uproot so much of your being and quit your job.

You have to remember that in the end of the day, that's what you want people to do. The people you want to apply are probably being treated really well at their current job so that they won't quit.
