Dear Mr. Bhushan,
If you don't mind, the following four elements makes your descripttion some what unbelievable:
1) Class '1' gazetted officer, as the classification stands changed for about three decades back and every Class-I Officer knows the revised classification of post:
2) The probation period you mentioned, as 3-3.5 years, seems to be quite wrong, as even extended probation is not likely to go to that much period;.
3) You submitted a bond of 7 lacs at the time of joining is also not understood, as I have not so far heard about any bond desirable from any direct recruit for class-I post, if made through UPSC ; and
4) You don't know which service conditions, as the probationers are duly given training through lessons on sevice conditions with reference to the CCS (Conduct) Rules during regular theoretcial classes during induction training programs, added with practical field training on the modules of training, for at least two years during probation period of a new recruit.
So, would you kindly clarify for which post of which department with bond of Rs. 7 lakhs and such a lengthy period of probation you have been recruited?
However, if you feel any hitch to inform openly through this forum, you may send details through personal email at sssfi2016& gmail.com
On receipt of your satisfactory clarification, I may like to guide you appropriately. In fact, if already applied, you have already committed a misconduct for not informing the competent authority.
However, in the mean time to some safe side, if already applied for the said exam on or before the due date for submission of online application, which is already gone 2 months back, you must inform the cadre controlling authority formally through an application about your intention to appear in the GATE 2017 without loss of any more time, as it is already very late on your part.
