I honestly wouldn't take that too much to heart.
couple of things:
with the slowdown this year...there's probably more competition.
and if you didn't do well on the test...that could be it...it could also be that they went by order of application submission...and yours was just behind a lot of others.
Keep your chin up.
do good work.
keep going to work every day of irregular ops knowing that eventually those days will come to an end. and keep doing your best.
you'll get to where you want to be soon enough. for right now, enjoy the journey.
