When I got the email in June saying that I was on hold, it said that my file would be reviewed again in June for a place on the alternate list. The email made it sound as if there was no chance of getting an acceptance until mid-summer, and not without going through the alternate list first. I was pretty disappointed with this, especially since I interviewed on the very first day and didn't see how they could put me off for so long not knowing how any future interviewees would stack up. But, it seems that there is some hope for those of us on hold, at least if Kazzar is any indicator. He interviewed the same day as me, got put on hold the same day as me, and got accepted directly off hold a few weeks ago. So it seems as if they have started to look at the hold files, and (at least a few weeks ago) it is possible to be accepted without going to the alternate list. However, I don't know how many hold files have been reviewed yet, and I don't know if all possible acceptances have already been given out (i.e., it will only be possible to go to alternate list from now on). The whole hold category is pretty vague, and I don't think anyone here is a definitive source for information on what your chances of acceptance are from it.
I've been meaning to talk to Gayle about what actions have been taken on hold files, but haven't gotten around to it. So if anyone else sees her soon, throw in a question for us holdees too, will you? 🙂
