sir,
In the recent selection for technician grade-3(signal) i was selected in South Central Railway.
Actually my educational qualification is B.E in Electronics and Communication Engineering and also i have completed MBA in distance mode from IGNOU.
I want to know, once i joined as technician grade-3(signal), is there any internal exams to get promoted to higher grade or to junior grade or to section grades.
And also tell me details regarding the pormotion pattern with the time taken to get promoted to that posts.
Another thing is that i am eligible now to write the SE (s&t) as an internal candidate of railways.
please assist me.
