I applied through a recruiter. The process took 2 months. I interviewed at Meta in Jan 2022
Interview
Lengthy. 7 interviews about half focused on leadership skills and half on engineering skills. The panel is looking for "signal" - a term they used repeatedly. In the end they are not looking for humans - just a collection of signals. Your resume and experience are irrelevant.
