The reason an employer should update company the company information is for the same reason you, as an employer, want a completed resume card from the virtual team member. When you post a job on the VPM site, your company information is visible. You will receive more applications and more responses to your messages the more information you enter into the system. Just like you are nervous about the person you are contracting with, the contractor is nervous that they are going to work for a real company that is going to pay them.
If your company information page has no website, about section and social media links, the contractor cannot get any information about the company. Thus, they cannot build trust. Thus, they do not apply to your job. Remember, you are marketing your job but more importantly you are marketing your company when you post a job on VPM Solutions.
