If there's one group I can trust to give me honest feedback about my LinkedIn profile, it's here on Manager Tools. Here's the link - www.linkedin.com/in/jonathangiglio/. Please feel free to connect as well.
A little about myself - MBA, mid-career, Product Manager looking to move into management.
Do I have too much detail? Not enough? I do have a CMD (Career Management Document) with all of my accomplishments that I use to tailor my resume.
Also, feel free to post your own LinkedIn profile in this thread if you're looking for the same type of feedback.
