see there is no hard nd fast rule 4 ur question....belive me...i myself saw occasions wer B.Tech was preferred to M.Tech so company can get 4 cheap.
bt tat does not mean u dont do it....many organisations tac tudents from iits iims only to show off abt their company.....so in my opinion..do M.Tech nd as soon as possible do MBA also....nd u no y all this wen u get equally good jobs wit B.Tech after some time working wen there is tie between u nd ur colleage regarding promotion...higher degree fetches!!!!!!!!!!!!
so do ur best wer evrer ur.......even if ur asked to sweep a room the man who asked u to do so must praise u!!!!!!!!!!!1
plz..rate me!!!!!!!!!!!1
