For masters there are tons of field to choose , even the smallest thing is important in a company . As you said you have done engineering from VJTI which is a good college to get a placement  , so i would advise you to start applying jobs from the campus . See the thing is during your masters admission in an foreign countries different universities have different criterias for admission for masters degree . Some universities allow students directly after they have completed their bachelor's while some want some work experience , some want good academics score plus work experience and some want only admissions related to their bachelor course and good entrance exam marks . So it is better to get some work experience and then go for masters . If you go for Masters in management like MBA most universities want some work  experience from students .

And the most important part is choose wisely your field of study as this will be your work life which you will study . Write you career goals what you would like to become in life and in which field you are best not good but best  .  If you are sure about your field then go for masters directly , good academics and good entrance exam score  will ultimately lend you in a good university and you will get your field of choice .
