• Reduces ramp time and misfit from misaligned stacks.
• Lowers onboarding friction and early incident risk.
• Requests architecture diagrams or sanitized runbooks.
• Aligns expectations on tooling, pipelines, and governance.

Which red flags signal rushed PowerShell hiring risks during interviews?
