I agree with you. However, learning the algorithms is different than preparing for technical interviews IMO.

I've learned many algorithms and implemented most of the ones I've learned, but if I haven't recently coded them repeatedly or studied them rigorously, I likely won't be able to code them up on the spot when asked to. But because I learned them in the past, I would be able to recognize which algorithm (from the ones I've learned) best suits the problem.
