dear Loku raj,

Some of the opportunities I’ll highlight :

Bachelor Degree (BS) : Through JEE.

M.Tech degree : Through stellar GATE score + interview.

MS/M.Tech (Research) : Relatively lesser GATE score & a good background of research+ interview/test.

MSc : Through JAM examination.

(RA)Research Assistant/Associate : Hardcore Research/Project background + valid GATE (sometimes).

hope you got your answer .

GOOD LUCK  :)
