I tend to agree with this sentiment. As my colleague aptly put, algorithms/data structure questions aren't really about whether a potential candidate can perform the job.

It's more about whether or not they are "one of us". I mean, if you couldn't be bothered to brush up on CS fundamentals, how can I trust you with the responsibilities that the job entails? That looks like a red flag to me.

FWIW, when I interview people, I ask actual problems I've run into, i.e. design and implement a sane concurrency system that's easy to reason about on an embedded platform with limited resources.
