Meta Intern interview questions

The first round was a 30 mins phone call with a recruiter, who is super nice. I was asked to introduce myself. Then she introduced the next interview process. I think this phone call was just to get me familiar with the whole interview process. The second round was a 45-min Bluejean interview with a researcher(I was applying for a summer intern position in FB research team). The researcher created a hypothetical scenario and keep digging deeper based on my answer. I'd say the question was pretty hard for a student with no working experience.
