Don't Just Inflate Your Resume.
Defend It.
AI tools can pad your resume to beat an ATS, but they cannot sit in the interview chair and defend the architecture. Citadel drops you into live-fire enterprise crises so you can fail safely, master execution under multi-agent pressure, and walk into the room with unshakeable competence.

Linley Hoang (Engineering Manager):
“Excellent partitioning approach by day. The SCQA problem framing clearly communicated why the runaway queries originated in warehouse tier 4.”
Isabella Garcia (Security Officer):
“Audited query against GDPR/NDPA rules. Zero customer PII was exposed in the unnested diagnostic logs. Passed.”
