I dont have an answer to your question but as there are here people with a lot of knowledge will like to add another question: How do I learn not to over-engineer solutions? This is the feedback that I received on a couple of homeworks from some non-FAANG companies. What can I read or what to learn to have this skill of doing simple solutions?
