Bhai probation period mein to 2 years service nahi ho sakti.
Matlab k apply through proper channel sirf woh he kar sakta hai jis nay 2 years continous service ki ho in any govt department.
aur yeh ap pe depend karta hai k ap through proper channel karna chahty ho k as fresh. Baad ouqaatb ap ka parent department noc nahi dayta to ap through proper nahi kar saktay. Is soorat mein ap ko decide karna hota hai k ap ki age within maximum limit hai ?if yes then you can apply or you should apply as a fresh candidate.
Hope you understand.
