Hey, as per lot of calculations and surveys Computer Science engineering is the course which has high preference and most paid salaries. For freshers the expected salaries is like 4.5 - 6 lakhs per annum. But it can increase a lot more depending on where you work and how much experience you have in that field. But if you are an IITian your salary can go up to 1crore per annum. Your skills and experience is all that matters to give you a most sufficient salary.
