There is a Civil Service Certification list and it might shed some light where you stand. I noticed for me there was an update not on list number, but where I stand within the process. On the update it says they have 225 Vacancies and how many ppl they called in to try to fill the position. They call way more than needed to account for the ppl who defer or don't pass drug screening....etc. Few days after I noticed the update under my name I received my second PE notice. Maybe it will shed some light for you. Link is below
