>90 days isn't enough time to close enterprise deals

I'm not sure why you think she was fired/assessed on the basis that she wasn't able to close enterprise deals within 90 days. The same tweet seems to refute this by saying "we can often tell within 3 months or less of a sales hire [...] whether they’re going to be successful or not". Presumably they're looking at various indicators (eg. size/composition of the sales pipeline, reviewing her sales calls and/or emails) and using that to predict performance.
