X Software Engineer interview questions

I interviewed with Twitter starting in late November 2020 and ending mid-January 2021. I started with a phone screen with a recruiter, then a one hour chat with my hiring manager to gauge interest (on both sides), then the final round of interviews which consisted of a 1 hour system design interview (for which I was asked to write a little code as well as answer questions), a 1 hour coding interview and a 1.25 hour behavioral interview (again with my hiring manager). I received an offer about 2 weeks after the final interviews. The process was very smooth and the recruiter helped coordinate and answer questions every step of the way.
