I recently had an onsite with FB. I could not produce a bug free solution for one of the coding questions and the other was okay. System design, product architecture and behavioral , all went good but it was really very unpredictable, interviewers din’t show a sign of like or dislike.
What are my chances? It was for E5. Will they evaluate my other interviews or coding should be the most important. Honestly, 6 months of preparation and then this has really made me very disappointed.
I think your chances are slim because you probably misinterpreted your responses (given that you had trouble judging the interviewers reactions).
