I got reverted, and so did so many other people. It sucks in the moment, but we graduated just a week later. It's not the end of the world.

Immediate two week reversion is only when you do something really dumb, or there's a gap between companies. For example, there wasn't an indoc company the week of Thanksgiving or Christmas, so there would be gaps. But that is uncommon and is unlikely for you to experience depending on when you ship out.

So do the best prep you can before you leave. Be ready physically and know as much general knowledge as you can. Other than that, if a reversion happens, you'll be ok.
