> In that case you might be screening for people who can talk but not actually code or people who can code but might not be the best communicator.

From TFA and literally the thing that started this whole thread:

> Furthermore, no matter what, poor technical ability seems highly correlated with poor communication ability – regardless of language, it’s relatively rare for candidates to perform well technically but not effectively communicate what they’re doing (or vice versa).

Right but that would also be true and exactly what you'd expect if interviewer mainly judged technical competency on ability to communicate. Since the form is self reported it's impossible to separate out whether the correlation is causal (poor communicators are poor technically) or due to interviewer bias (poor communicators have a harder time convincing interviewers of their technical chops) or even other factors (being flustered hurts both a candidates communication and technical skills).

This is after all an advertorial piece of data spelunking not a study.
