Interviewing _is_ a filter. Each step where you eliminate candidates is a filter; that's what that word means. I think what you're really trying to say is that blind filtering is bad (okay, you said this part explicitly) and you think that HackerRank is a blind filter. Unfortunately, this is pretty obviously not true. HackerRank uses quite a bit of data. Arguments that HackerRank is using the wrong data, or using what data it has poorly, would make a lot more sense than what you've said so far.
