I applied through a recruiter. The process took 3 weeks. I interviewed at Meta in Aug 2015
Interview
Was contacted by Facebook recruiter via LinkedIn. I had never considered applying at Facebook but the positions mentioned seemed interesting. Phone screen with a person not on the team I was applying to. Asked questions that have been mentioned here many times over several years. Took over two weeks after the screen to get any feedback.
Recruiter call was pretty standard, first round was 2 Meta tagged LC mediums in 45 minutes. On-site was 2 coding sessions of 2 LC mediums, a system design interview and a behavioral interview with an engineering manager.
