Meta Software Engineer interview questions

The whole process went by incredibly quickly. After applying directly to a recruiter, I completed a coding challenge through HackerRank as part of the screening process. I then received a call from the recruiter to walk me through the interview steps, which was a very kind gesture to make towards an intern. After that, there were two phone interviews, each just a week apart. Both went rather smoothly, but I was rejected by email just hours after the second interview. While no feedback was provided, and although I thought the technical portion of the interviews went well, I have a hunch that they were looking for someone with more university and extracurricular project experience, something which I lacked.

Facebook came to our college for hiring of interns on the campus. The process included one coding round. It was carried out through Hacckerrank platform. I couldn't make it to interview round but those who did were screened with 2 telephonic interviews. There was only one question in coding round which was to be done in one hour.There was resume shortlisting after that. Those who were shortlisted were called for interviews.
