Dear Krishna, once you qualify for JEE Mains and you join your Bachelo's degree, you study in an Institution for the next 4 years. There are few things that need to be considered here. First things first, you will be a fresher and the on campus placements are different for every institution. So, your placement recruiters visit your campus based on the type of Institution it is. The truth is that if you get into a mediocre indtitution, you can't expect Microsoft or Apple to turn up for placements. So your first goal should be to get into a very good college. And even if its off campus placement, few Companies want you to be graduated from Tier colleges. The second point to be considered is the inflation rate or the rupee value. The value of the Rupee keeps changing as often as possible. And with every inflation or deflation, the cost of living is affected. So the package what is considered decent today might have to be upgraded accordingly. So assuming a package after a durationnof 4 years is not possible. And finally, lets say Apple or Microsoft have landed up for on campus recruitment and the package is decent. But the most important factor is your percentage in your accademics. The aggregate in your accademics and your performance in the interview are directly proportional to the package you get. The better your marks and better the performance in your interview, better is the package. So what happens down the lane in 4 years is totally dependant on how you fare every day in these 4 years. Good luck
