AFAIK, the staff who began at low rank is Halab (one of the most recently hired staff, since 2018 maybe), from Full Member rank if I am correct.
I was just a member at the time (with the same number of merits as the OP), but for local sections the requirements are probably lower.
Thanks for correcting me. Maybe when I saw you as a staff, you were a Full member. I did not know you before that day so maybe I missed your first day as a staff and correspondent rank (member as you disclosed).
