What I found helpful early in my career:

Book: Code Complete - Steve McConnell

https://www.amazon.com/Code-Complete-Practical-Handbook-Cons...

A bit dated maybe, but still very informative!

I second Code Complete.

The Pragmatic Programmer and Code Complete were integral on my first job.

Thank you! I think this one will be helpful for them and for me.
