(Following is not in accordance with standard horary practice and uses whole sign house format)
Unfortunately (HOPE I'M WRONG!) it does not look favorable, at least according to the methods I use:
-he = 7th house = Pisces = Jupiter
-his career = 10th from 7th = Sagittarius, also = Jupiter
-when significator is the same,Ankara horary evaluates the condition of that significator to estimate the answer:
-Jupiter is retrograde = -
-Jupiter is in detriment in Gemini = -
Further, Jupiter is in the 4th house from the 7th, indicative of "staying home".
I would have to, he will probably not obtain this position, at least over the near future. (Will be GLAD if I am wrong in this!!)
