A recommendation on LinkedIn is a great way to increase your chances of getting hired, so if you get a request, you can earn some goodwill (and hopefully an equally strong recommendation in reply) with a well-worded review. The Daily Muse has a 5-step, 5-line, 5-minute guide for amazing recommendations.
The basic premise is to be specific and touch upon each aspect of the person's professional life. You start with a knockout line that stresses how awesome that person is, follow it up with a one-line explanation of your relationship, share a standout skill about their work, share a congenial personality trait and end with a solid recommendation. Here's what the template would look like:
