Meta Internship interview questions

Telephonic Round : the interviewer spent a few mins on introducing herself, and asked me a few basic questions. A couple of general questions about my resume, had to explain one favourite project in detail. Following this, I had a coding question: minimum window substring, and about 30 mins to solve this.

I received a message from a recruiter and applied through him. Then I had one phone interview with a another recruiter. then we scheduled technical phone interview. The process was quick.
