I was connected with a higher up via a recruiter. I had requested to be contacted through my professional email but was instead contacted directly through Facebook, which I don't use. As such I was two days late to respond and received a cold shoulder. The recruiter reprimanded me and forwarded Roostify's feedback that I was, "not taking the company seriously and am extremely unprofessional."
Several of my peers have interacted with Roostify in various ways, including as software consultants. None have anything positive to say about the company's communication skills or their handling of projects.
