When the HR folks emailed me with a couple Indoc class dates for me to choose from, I made it clear in my response that I’d move mountains to make an earlier class if somehow a spot came open. They said “thanks, that’s rare but we will keep you in mind”. About a week out from the class before mine I got a voicemail from them saying a spot opened up, they’d called about 3-5 people, first to respond gets it. I guess I was lucky and was the first to call back.
I asked in Indoc who bailed that allowed me to get in early. They said it wasn’t a new hire, but one of the 5-10 return to work folks coming off long term disability or long term mil leave that fell out. I think most of the supposed “no-shows” fall into that category.
