I’m Michael. I was a principal engineer at Facebook from 2009 to 2017, where I was the top code contributor of all time and also conducted hundreds of interviews. I recently co-founded Formation.dev, an engineering fellowship that trains and refers engineers directly into big tech. Ask me Anything!

Hey, E6 -> E7 is a very large jump. Approximately 15% of the company is E6 and under 2% is E7. At Facebook they have these "archetypes" which kick in at E7, so you have to be solid all around and like exceptional in one of the areas. For me, I was the "coding machine" because I cranked out ungodly amounts of code and motivated others in the process. I can't comment about Twitter's process, but in Facebook speak, you might be doing great at everything, but you need to now build momentum around your superpower. Are you solving problems no one else can solve? Are you cranking out tons of code? Are you saving millions of dollars via elegant solutions no one else can think of? If you can keep doing what you're doing and then triple down on your superpower that might be the difference.
