I don't agree 100% with the author on not asking them algorithmic questions. Its a process on how they go about solving it rather than just the outcome.
Maybe for the web developer position, you might not need such type of questions, but for a full stack developer the answer is unequivocally yes.
I made a mistake by hiring someone who knew django [who originally wrote plugins in WP] and the coding was just plain horrible. One such example.
`for foo in queryset: foo.prop = 'i m bar' foo.save() ` Simple things like this, where a good engineer would know because of O(n) nature of the code, the so called programmer didn't.
And then there are guys who fork every possible repo, have blogs about how-tos, etc but really can't code for nuts.
