This book was really useful to me as someone more interested in the technical leadership track than the people management track. The early chapters covered content useful to the track I'm interested in. The later chapters helped improve my understanding of how various levels of leadership work at tech companies and the various benefits/struggles/tradeoffs/etc., which are useful for better understanding and empathizing with both my immediate manager and people farther up the reporting chain.
I really appreciate that the book focuses on advice specific to working in tech while providing useful resources to read later for general management advice. I will definitely be recommending people I work with add this to the list of books for managers and the management-curious to read.
