I'm extremely well calibrated here. Conducted 400+ interviews at Meta.
You are likely borderline. For an initial screen, it depends a bit on the difficulty of the question and how clean your code was and how well you communicated your thinking process.
The 5 mins of Q&A cutoff is standard pacing and doesn't indicate anything one way or the other.
I advise people all day long about preparing for Meta interviews and my advice here if you make it to the onsite: manage the time better yourself - if you acknowledge there might be something better than O log (n), you can say "Given the time, I feel confident about writing out a clean O log (n) solution" and then write it super cleanly. You might not get a "strong hire" on the interview but you are more likely to get a "weak hire" and a "weak no hire". You can also discuss verbally the O(n) if you finish everything early and get some partial credit.
