I've used Climber for over a year now as a way to fill job positions that I am working on. I place candidates with companies of all types from small startups to companies like ATT. I've always been happy with their service, responsiveness to my concerns and their professionalism. Have you ever tried to get someone on the phone at the other job sites? Its als worth noting the people I have placed in jobs because of it were happy with Climber as well.
