It appears that these closures were part of the Structured Tag Clean-Up Initiative for the careers tag, so this was coming. The short story is that having a career tag invited a number of off-topic questions, so it was decided to go through and remove the tag and evaluate all of the questions to make sure it was appropriate.
At this time, there is no general purpose career Stack Exchange site. The closest thing is The Workpace, which is still in the committal phase. It's about 70% to completion at this point. However, the general practice is to not move questions until the site is out of beta (or at least it is well-established as to what is on-topic and what is off-topic on the other site). In addition, older questions or non-constructive questions are never moved (first rule of migrations: never migrate crap). There's a more detailed discussion of this concern here, in another Meta question.
So, at this time, all career questions that apply to all careers and do not require the specific expertise of professional software developers will be closed because they are off-topic here. If you feel that you can salvage one through the use of heroic edits to make it constructive and on-topic, please do so and try to get it reopened (including using chat, Meta, and moderator flags as appropriate).
