Lillian joins Mihaela and Pascal in this episode to talk about Facebook Stories and how it took shape from a new sharing surface developed by three engineers to the mature product it is today. You'll learn about the challenges her team faced while trying to scale Stories from a prototype and the performance implications of introducing new types of content as well as functionality at the top of News Feed. If you've listened to our previous episode featuring Balazs, who's been an engineering manager for some time, you can now hear about this role from the perspective of someone who's just recently become an engineering manager and is now going through the transition from an Android engineer to a manager.
