Well, I'm currently spending time on going over the Coursera Algorithms course by Sedgewick and Wayne in addition to doing at least 2-3 leetcode problems daily. I'm thinking of having a periodic check-in and code-pair session where we can review and challenge each other. And do the same for systems design/behavioral at some point if that goes well. I have tried pramp in the past and it was useful...until they got bought out. Look up my email and in my profile and hit me up.
