This wasn't a technical interview. This was a phone screen. As dumb as it is, having non-technical recruiters do a "technical" phone screen like this is increasingly common. I don't think this practice is completely justifiable, but part of the root cause is the enormous volume of grossly underqualified people who apply for any particular position. It takes a hiring company a large amount of work to vet a candidate but it takes a candidate nearly 0 effort to apply for a job.
