Ask your contacts! At the bottom of your profile is a section to leave voice, or written comments. This is the perfect spot for your trusted network to endorse you. ITHerds recommends recorded audio references (You can record up to 1 x minute of audio). However, to be able to record audio they must be signed in, so will need to create a profile, but once set up, if they are not job hunting they can go to ‘My Account’ in the menu, and mark their profile as only visible to them (preventing it coming up in searches).
