Meta Software Engineer - Internship interview questions

I got a phone interview screening through a referral. The recruiter got back to me within a week and scheduled a 45 min phone interview. The interview consist of two easy/medium leetcode questions on the phone.

Got referred by a friend, then shortly afterwards had a phone interview with 2 medium difficulty technical questions. Had an upcoming deadline so they very quickly notified me of my onsite interview which occurred the following week. That also consisted of two more difficult but not impossible technical questions. Recruiter was very on top of things and gave me my decision within the next day or two.
