Indubitable that MoD and FGO are prestigious organizations, being there is dream until one is there.But some people left AD MoD/ AD FGO when allocated in PMS-12&14. Being PMS there is more horizontal and vertical mobility as compared to MoD and FGO,however one's personal preference also does matter and some PMS-12 officers even recommend foreign funded PhD and University lectureship as better options with a rationale that being PMS 37K starting salary, all the day long files even at home while being lecturer(BS-18) rapid promotion, foreign visits, research grants, remuneration for evening classes etc. etc. while being in services, they do benefit with due favour to friends and family but their own life is full of hardships.
There are always better options.
@Sir Imibindas, Tehsildar can provide more vertical and horizontal mobility as compared to many other jobs. But it can only be conceived by a person who has experienced it,experience is one of the best teacher, experience a job and once fed up just abandon, if we find a better opportunity, sir! people will realize it after experiencing what you have experienced. Enthusiasm and charm remains for the transitory period (Nai Dulhan k 9 din) and later on people realize that it was not a destiny (in fallibistic approach). I was also looking for AD FGO, for the up-gradation of a scale and ultimately pay, but it was not final goal and it was telephonically discussed with one of the selected (AD FGO) members of discussion and he was also aspiring for CE-17.
