Completed my Amazon SDE-2 Loop. 3 Rounds went great but last LLD round was average or Below Average. Do I have a chance?

Rounds 1–3: Felt like "Strong Hires." One was HLD/System Design, where the interviewer seemed really happy with my scaling trade-offs. Two DSA rounds went smoothly—solved the problems (Medium/Hard

Rounds 1–3: Felt like "Strong Hires." One was HLD/System Design, where the interviewer seemed really happy with my scaling trade-offs. Two DSA rounds went smoothly—solved the problems (Medium/Hard) with optimal complexity and had good discussions on LPs. Round 4 (LLD + Bar Raiser): This is where it got shaky. The task was to design a File Filtering API. The Good: I used the Strategy Pattern to make the filters (Size, Date, Type) extensible. My code was clean, and I handled the Leadership Principles well. The Bad: I completely missed the Composite Design Pattern. I struggled to elegantly represent the file/folder hierarchy and ended up with a slightly messy recursive logic instead of treating them as uniform components. The Worry: This was the Bar Raiser round. I know they have veto power and they really look for "Logical Maintainability" at the SDE-2 level. Has anyone been in a similar scenario earlier? What are the chances, and do they provide another round for these situations?
