Facebook | Phone Screen | Verifying an Alien Dictionary

I got a call from university career fair. My phone screen was conducted on the 7th of Nov. Duration was 45 mins. The following were the questions:

  1. Tell me about yourself
  2. https://leetcode.com/problems/verifying-an-alien-dictionary/
  3. Questions for the recruiter

The interview went well from my side, where I explained everything neatly (first 2 things from the above list). I kept asking in regular intervals whether the interviewer is able to understand what I am explaining or not, and to let me know if anything is not clear. The interviewer seemed to be satisfied with the solution, and did ask me about the complexity of the code, which I mentioned correct with explanation for the same.

I got a reject today, which is 6 days after the interview. I am not sure what went wrong, like whether they wanted me to solve two questions within 45 mins (that's what I have seen usually), or I am rejected for some other reason. If anyone has anything to suggest, please feel free to comment. Thank you.
