Meta Software Engineer - Internship interview questions

I got an email pretty fast after applying. In that email a very helpful recruiter described the process to me. She provided links to resources that would help me prepare and I reserved a slot for a phone interview. She called, we talked a bit about my past positions, my skills and my academic advancements. That was the first stage of the interview, which I passed. The second stage involved live coding. I was again called by phone and was given a programming task. I failed to complete it and was a week later rejected

The whole phone interview process was pretty straight forward. I was asked to solve some algorithm questions, using my preferred coding language. The key point of getting a successful coding interview is setting up very clear objectives before real work: what does the question mean, what are the meanings of concept mentioned in the question, what data structure or algorithm I am going to use and can my solution compute the expected outcome.
