To a large degree yeah - performance in "stupid algorithm games" is basically perfectly inversely correlated with "years since undergrad CS courses".

It's more of "years since last studied algorithms". University algorithms classes are useless for these types of interviews for the most part when 90% of the focus is on the proofs.

Most people I know spent time studying by themselves outside of class/class material.
