Hello,

I had telephonic interview with FB. The question asked was https://leetcode.com/problems/longest-string-chain/ [ Not Exact but little trick was there]. I was able to solve the problem but it took some time to optimize the solution and go over various cases. The logic was right. Problem is we ran out of time so interviewer didn't ask another question and mentioned that 1 question is sufficient for screening. Really don't know what does that mean?
