Screwed technical interview but did a great job in beginning rounds

Applied for an leadership, cyber security and Akali shortlisted at the beginning, I had an interview call with recruiter. She was pretty impressed and referred me to a senior manager. We schedule a 30 minutes call but it went up to 1 hour. He was really impressed with the soft skills as well as my technical skills, and then I had an interview with director and a recruiter. Call me back said that the director was pretty impressed and things felt so good And she even put emojis in the messages which she never did before in our conversations, and I am thinking i’m a final candidate, but after again, they have sent me another link with another director where both the teams collaborate a lot, and I just had a call with the director where he was super technical. He went into in depth of the questions he have gone, he has gone into all Deep networking questions where I was pretty nervous. I was blocked out and II was almost ready to unplug my desktop, but I answered few of them, but I feel like my performance is 4 out of 10. He told me he’ll give his feedback to the director of my role.
The other two interviews were 10 out of 10, but this one I screwed because it was so deep into technical and I don’t know what’s the outcome
is there any chance have you ever screwed the technical round or the deep technical questions? Just answered few and still got an offer ?
