what should I do, to go In defence area as electronical Engineering and what is the salary ?????

hi,

after completing your bachelors degree in engineering, you would have two options like go for higher study or search for job. in case you are interested for defense, DRDO hires candidates who has excellent gate score as scientist B post. Time to time  Indian army release notifications for hire engineers. but since government vacancy is very less and due to pandemic it may delay. my suggestion is after completing college try to get job in relevant sector to get work experience, also try for government job simultaneously.

hope it would help.
