See both Mechanical Engineering and ECE are the fields which have a lot of applications in day to day life. But the sad part is when ever you will see the placements then you will find the majority of the Mechanical jobs are very low paying and apart from that most student will not get a job in there core field. As a result if you go for Mechanical then the maximum possibility is that you will end with a non core job. So if you wish to go for a field which you have the job of the field itself then go for ECE. The possibility of getting a core job in ECE is much better than that of Mechanical.
