One ok onsite round at Google

I recently interviewed at Google for software engineer position. I had 4 rounds plus a lunch round. I did well in three of those rounds (finished with 5-10 mins left in all of them to chat with the interviewer). In one of the rounds , the interviewer was supposed to ask me 2 questions (he mentioned that in the beginning). I was only able to finish 1 in 30 mins. I asked him to tell the second question. He asked it and told me to just discuss ideas as we didn’t have time. I gave some bad ideas in last 5 mins and we concluded the interview. Any thoughts about the chances of getting an offer ?
