EDIT: Since you are talking about coding like at a top company, one book that has been sitting on my shelf for a while, but I haven't gotten around to reading yet is "Software Engineering at Google: Lessons Learned from Programming Over Time" (https://learning.oreilly.com/library/view/software-engineeri...)
Thank you ! It's my birthday soon, just ordered the last one :)
I learned how to code at a bootcamp. It's fast and it's not deep knowledge (they teach you the "how" not the "why"), I'm learning fundamentals of CS on my own to bridge the gap.
But practically, a few things I'd love to learn :
1. How to write optimized code (best practices ie. in terms of space and time complexity)
2. What is a great software development process ? Design -> Code -> Test ? That kind of process I'm very curious about. Learn how, if I launched a product, should do in terms of steps of development.
