3 rounds with 3 separate interviewers on coderpad, 2 LC mediums each round from the top tagged in Meta LC sorted by 6 month filter and no behavioral questions at all.
I interviewed quite late in the season (spring), but after the technical round, it took 8-9 weeks before the recruiter got back to me with Engineering Leadership's decision. I was in touch with the recruiter regularly; it seemed like there was a backlog of applications, and very limited intern hiring left at that point.
I applied through a recruiter. The process took 5 weeks. I interviewed at Meta in Jan 2025
Interview
