Whether or not its in the job description, hiring managers want someone with proven:
Attention to detail – mistakes make managers look bad
The ability to juggle multiple priorities – (s)he is going to ask you to do a lot of things at once
Organizational skills – if you’re not organized, you’re not going to be able to be as productive as other candidates
Don't just tell your interviewers you have these skills, give them examples by working them into your stories. It could make the difference.
