I wouldn’t do 61B projects to learn how to interview; they aren’t too relevant because they focus more on writing software rather than data structures (and aren’t of the greatest quality IMO).
The lectures on heaps, arrays, linked lists, and MST are worth reviewing. Also, I would try implementing each DS/A from scratch, and do Leetcode to brush up. If you want to learn algorithms super well, then do the first half of CS170 (stop after DP) from Berkeley, including the homeworks, which are challenging.
Credentials: did undergrad at Berkeley, also worked at FAANG.
