I interviewed with triplebyte about 5 years ago. They rejected me saying that my editor skills were good but I didn't pass the mark because I couldn't find enough bugs in a program fast enough while being watched. This was really good for me as my subsequent decisions took me to where I'm now as a lead architect of a US startup, earning 5 figures USD while living in LatAm.

On related matters. I know several companies that have pivoted out of the "hiring/recruiting" space because apparently that space is not easy to scale/automate.
