Hey,
If we are talking about trends, then at present date, when everything is becoming digital, the demand of 'good' computer engineers and electrical engineers is increasing contantly and at present, they are being placed with highest of packages. Mechanical engineering is also a good branch which has a significant scope and provides good packages to students.
But these are merely trends. Most important is student's interest. Just taking the demanded branch will not give you a decent placement. It will be only possible when you will work hard for it throughout your engineering. And working hard is only possible when you will find your stream exciting. So make sure you don't go with the trends and choose the stream that excites you.
