That is the course.

You have worked the deployments most engineers never see: disconnected, regulated, multi-tenant, and the ones that were already on fire when you arrived.

Nothing here is a certificate, because a certificate from us would not mean anything. What you have instead is the vocabulary to follow a real deployment conversation, and the judgment to know which question the room is actually asking. Go use it on the question bank, then go use it on a loop.

If it was useful, send it to the person you know who is interviewing. That is the whole marketing budget.
