I think the answer to the age old problem of "do algorithmic interviews help" is: it depends. Testing hard algorithms is probably not going to help in figuring out if someone is a good front end engineer who is only expected to build web or mobile apps. It will however be useful to identify if someone who's expected to regularly design system components, like say a cache layer for something, to actually understand the drawbacks of different caching strategies. Algorithms should be tested, but conditionally. On the other hand, every engineer needs to know data structures and should be tested on them.
