Your AE promised the customer a capability that doesn't exist, the contract is signed, and the customer is holding you to it. Handle it.

The capability isn't real, the ink is dry, and the customer found out from you, not your AE. Throwing sales under the bus and quietly building vaporware both fail. Here's how to reset the expectation without breaking the account or the internal relationship.

FEDITOR'S NOTE

The disqualifier is telling the customer 'sales oversold you,' because it's momentarily satisfying, blows up your own company in front of a client, and teaches the customer your company can't be trusted as a unit. The held-back follow-up is 'the customer threatens to invoke the contract or churn, what now?', which moves it from an engineering reframe to a commercial problem you escalate rather than freelance. Interviewers watch for whether you fix the expectation and the upstream process (getting into deals before they're signed) rather than just the one fire.
