Sounds like you're dealing with some workplace politics or personal situation that went sideways. Without knowing the details, I can't say if it was about qualifications or just typical human BS.

People get passed over for all kinds of reasons - sometimes merit, sometimes politics, sometimes just bad timing. The real question is: did you learn something from it and position yourself better for next time?

Don't let one setback define your worth. Focus on stacking skills like you stack sats.
