Meta Software Developer Intern interview questions

The interview process comprised of a technical round held at my university. My interviewer was very polite, and patiently explained the problem statement to me. I asked for further clarification of the problem statement, to which he mapped out the problem on the whiteboard. The challenge involved writing code in whichever language I was comfortable in. The problem was to convert roman literals into its equivalent numeric value. I used the whiteboard to solve the problem. I walked the interviewer through the solution and he asked questions on edge case scenarios. Overall, the interview went ok, but I did not receive a next round call. This was probably because my solution was not optimal and upto their expectations. It was a good experience and I learnt a lot from it

Got the first interview through school career website. Process consisted of 2 on-campus interviews plus a phone interview since I was a borderline case.
