When i submit a "resume, coverletter, interview answers, ..." all of my personal info(PI) goes into a black hole at company {X}. I don't know what they do with my PI, dont know how they determine who is a match and who is not, essentially I am giving up my time and my PI to a process I have 0 control over. If I were to submit some "actual work" and that "work" was assessed and evaluated by {any} company in relation to others submitting "work" in what I believed to be a fair and open process, I don't think that I would have a problem using this process with any company.
