I have go crecked on jrf after what do then be receiving me job

Hii Shnkarbhai!
Although your question is not clear, I will give you the answer based on what I understood. If you crack the UGC NET JRF exam, you get a grant to Persie research in your respective PhD field. You get many benefits along with it, such as JRF fellowship, job as an assistant professor in top universities, promotion, opportunity to join PSUs etc.,
Hope this helps.
Good luck!
