I enjoyed this book. It is easy to read and relatively short. Not all parts are relevant for everyone, since while progressing through the book you go through the career ladder and end up with what a CTO does. This is good, because you can easily skip these parts or deliberately read those if you report to one of the higher levels or heard about what people on these levels do and the book might help to make sense of this.
A big focus is on 1:1, but there is also a lot of tips for standard situations as well as short illustrations of the patterns or antipatterns.
Most things will apply to management in a tech organization in general, you thus would need to swap out "IDE", "Toolstack", "Coding" for whatever your discipline uses and does.
