Meta Intern interview questions

Face-to-face interview with a Facebook employee. Asked me one technical question. The question was kinda tough and did not expect such a question in a short interview. The interviewer himself did not seem very experienced and was not very helpful in giving hints or helping me out. Moreover, later on, when I was writing the solution, he started ignoring what I was talking and starting browsing his phone, which was kind of insulting. During the solution designing process, he was more leaning towards finding out flaws in what I was saying rather than helping me out

Applied online, and got an email from a recruiter two weeks later. A week later I had a phone screen with an engineer, and a few days after found out I was rejected. Overall, I was really happy with how quickly Facebook went through the process--definitely makes me more interested in wanting to work there!
