Roblox reject :-(

Got a reject from Roblox after Onsite
1 coding - finished, optimized, follow up done
2 design - drove everything from my side, interviewer interrupted only when we want to focus on specific area, did estimations, alternative solution, tradeoffs, security.
1 behavioral- talked about my recent project where I took ownership

Personally thought I did well since I don't see any bumps throughout the process.

Bizarre to get a reject via email. I wish I get some feedback.
