Hey Samatha Gurram,
No, You cannot apply like that. If you are studying in JNTU that doesn’t mean you can attend any of the JNTU branch for placements. If it is a pool drive, If the university allows outside students to participate in the placement then you can attend for that particular placement. Else you cannot as however you want. However the placements at JNTU Karimnagar are also best.
