Hi, I recently had my onsite interview with Facebook and my MLE interview lasted 1 full hour instead of 45 minutes. The interview was very friendly (I think I was able to answer the questions and propose a good design) and the last 15 minutes was just the interviewer (a manager) talking to me about their different teams, the WLB, how the bonus policy works, etc.

Should I take this as a positive sign? or is this just standard? Just to give more context this was my last interview round, in case it matters.
