ما أكبر فشل مهني واجهته، وماذا علمك إياه؟

1. Pick a genuine, meaningful failure (with distance/perspective)
2. Own your specific role — don't spread blame
3. Show what you learned, concretely
4. Prove the lesson stuck — how you've acted differently since

S: As a new tech lead, I pushed a major rewrite I'd championed.
T: I was sure it would pay off and didn't stress-test that belief.
A: I underweighted the team's concerns and the migration risk. The rewrite ran
   six months over and we eventually rolled back part of it. I owned the call
   in the retro rather than blaming circumstances.
R: I learned to pilot big bets and seek dissent before committing. Since then I
   run a pre-mortem on any large initiative — my last two shipped on plan.
