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!

Well there's title inflation :D. I remember I interviewed a "Vice President Engineer" once and was so confused. The candidate was a solid E5 senior engineer, and we both found the title kind of funny. Joking aside, I think the work ethics and intensity are similar, but ownership mindset is a tiny bit different. At Facebook, an engineer is an owner, responsible for their code, and they feel pride in seeing their code shipped, and then improving it to make it even better. The mindset in MBB is a little more about doing well on a project and getting good reviews from your clients and partners. I might be zooming in too much, but that's now I see it.
