There was initial interest when I applied for a technical writer position. Several Kforce executives visited my LinkedIn page and a week later I received a call from a recruiter who said she might have a temporary job for me. I asked her to send me more information but I didn't hear from her again for a couple of weeks.
When she called again I reminded her to send the job description. After reading it I indicated by email that I was very interested. I never heard from her again. Draw your own conclusions about doing business with Kforce.
