Meta Software Engineer Internship interview questions

I interviewed on February 16, 2021, for the London office. It was a 45 minutes interview online on codepad. First 2 minutes are an introduction of ourselves between the interviewer and myself. Then he asked me 2 questions. He asked me two questions. The first was easier but the second was harder and needed some time to grasp. I ran out of time at the end that I couldn't finish the second question. Tip: you should be fast and efficient.

very comfortable interview process. I had 2 phone interviews. Both were algorithm based. each interview had 2 questions to be solved in around 15 mins each. The interviewer provided hints in case i was missing something
