Hello Aspirant,

First priority should be given to where your interest lies. If you feel computer and its working fascinates you, then you should be choosing Computer Science engineering. But if you are more inclined towards machines, then you should be choosing mechanical engineering.

 Depending upon today's scenario, computer science engineering provides greater opportunities compared to what mechanical engineering provides. But, if you are interested in what you are learning then there will be no hurdle in getting a good job.
