Nowadays I don't have much time to maintain this project anymore.
I started the project when preparing for coding interviews when graduating. If this is your goal, too, then there might be better resources in 2021 to prepare for that. Here are some books that I recommend to friends who are looking to build a solid foundation.
Cracking the Coding Interview by Gayle Laakmann McDowell is a classic, which covers most of the questions that get typically asked in FAANG interviews like array and string manipulations, sorting, and searching.
System Design Interview by Alex Xu is more focused on typical software architecture questions, e.g. back-of-the-envelope estimations as well as making services performant and fault tolerant.
Note: These are Amazon affiliate links and I get a small commission if you end up buying a book. This helps me work on OSS in my free time.
These books in combination should give a good overview of what to expect in a typical interview situation. The repository can still serve as a nice companion while working through the chapters from the books.
