I’m a backend engineer with 5 years of experience and after taking a couple leetcode-style coding interviews for the first time in 5 years I’ve realized I do not have the DSA chops needed to pass a lot of these interviews, and that simply grinding the problems is not efficient enough. I have a CS degree, so the concepts are familiar, but I need a pretty deep refresher in order to start passing these problems. What would you recommend for someone who doesn’t want to start from the beginning but also needs something deeper than “this pattern means you need to use a depth first search” or whatever.
