Hello,

In the external career site , we have department field which by default is picking only the highest opening schools and the followed by others. We have almost 100+ schools approx and this should be a huge list and should have all the departments which are in the system. Also it should be in chronological order by alphabetically at least which will be easy for candidates to search within.

How presently the system is working is if i have a job B with 15 jobs with same department, while A with 2 jobs , Now in career sites its coming first as B(15) then A(2), while we want it come in alphabetically order so it should be A(2) then B(15)
