I'd put a call in to your recruiter or the HR person who sent you the onboarding info. They gave the impression that the whole Summer residency is cancelled and that they are not planning on hiring...
She didn't give specific reasoning, just that due to the hiring freeze they were cancelling all onboarding activity. The hospital in Austin lost 3 times more money than they projected it would, so...
Pretty sure they rescinded offers for the whole Summer cohort.
Any ideas what you're going to do? I'm at a loss, and she said they wouldn't be hiring in the fall
