is it possible for a stat board/ministry to put job ad on the Careers@gov for the fun of it (or watever other reason) without any actual need for candidates? Or am i applying too early (graduating next year may)?

I applied for one of the position on 8 Oct and the status has now changed to 'kept for reference'... and it is not even the application deadline yet. I am quite surprised as im expecting a first class hons (CAP safely in the range), has a more than relevant deg (is a rather specialized role and i have a second major that complement wat the position entails), relevant internship experience... and it did not indicate how many years of exp preferred, so it sld be an entry level position. i was expecting an interview at least.
