The process took 2 days. I interviewed at Meta in Jan 2010
Interview
For interns: 2 rounds of on-campus interviews. You need to answer at least 3 questions in the 2nd round. The interviewers are nice and supportive in general, and helpful if you need clarification of the problem. Both interviews are entirely technical. On average, you need to solve one question in 15 mins, and that includes coding on paper and testing with some of your own cases.
Two rounds of leetcode
Each round had two medium hard leetcode questions to be solved in 45 mins.
Pretty clear communication process.
Recruiter was helpful and very communicative.
No focus on behavioral questions as it’s an internship probably
It was great but there was minimal communication on whether or not you get accepted or rejected. I only got to the first round assessment. Don't know what happened after that.

Multiple coding interviews assisted by a person working at the company. Questions ranged in difficulty and type, thoughts were meant to be said out loud. Syntax was not important but thought process was.
