From our viewpoint, placements depends on the college in which you get admitted to. So if you are very keen on placements alone (at the end of B.Tech), kindly enquire about the same with friends or other relatives who are in that college.
Like what was pointed out, the prediction of future is left into the safe hands of the experts. We do not risk doing it.
But what we have seen is, be among the top in your class, you are better off in ANY COLLEGE with ANY COURSE !
All the best !
