Meta Software Developer Internship interview questions

I applied online in January and received a referral from another intern after a few weeks. Heard back in early February, but didn't receive a reply for a few more weeks. Received an interview request at the end of the month. The interview was a little weird, since the question seemed more knowledge-based than other technical interviews. I was told I was moving on the next day. Was given a second interview 2 business days later, which was a little less knowledge-based. I thought this one did not go as well but I received an offer after 3 business days.
