This book is basically what I was hoping and expecting it to be: a first-person perspective on management at a modern-day tech company, with accompanying insights on how to do this job in a successful and rewarding way. I frequently had to suspend by annoyance at the general "Lean In"-feminism style of complicity with the dysfunctional and abusive power structures that underlie tech companies like Facebook, so I can't really recommend it uncynically, but it definitely gave me a lot to think about. I especially liked the concrete examples of questions to ask reports during 1:1s and blueprints for successful meetings and interviews.
