This is no different to Codility or Hackerrank which both do the same automated assessments that this also provides. I'm afraid that this is yet another useless screening tool that unrealistically judges engineers based on 1 - 2 hour long programming sessions which doesn't help in finding qualified candidates.

I'd rather just stick to asking candidates about their open-source patches / contributions to large projects to cut the 80% of those who don't make it, than to use these tools which are a waste of money.
