Meta Software Engineer, New Grad interview questions

I was able to get a referral and had the recruiter contact me via e-mail who arranged a coding phone screen after a month. The interviewer was 15 minutes late and seemed very disinterested in the whole interview. He did not ask me any behaviorial questions and just cut straight to coding.

One phone interview consiting of one medium algorithmic question. After 2 weeks, I got invite to onsite interview in Menlo Park for (3 rounds , which includes 2 technical and 1 behavioural)
