Transition to a Software Engineering Manager?

After being promoted to a staff engineer or an equivalent level, most of the engineers will face a challenge: continue to grow as a senior engineer(TL) or transition to be an engineering manager(EM). In this article, I am going to share my observations at FaceBook.

Disclaimer: I am not holding any engineering manager position at FB. But, I have a couple of mentors who are managers now. And one mentor even transitions back to a TL, after working as a manager for a year.
