IT jobs are good for freshers because the salary is good. But as you keep on getting more experience, the salary hike gets less. In non-IT jobs, though the initial salary is less, hikes and salary for senior posts are good. So I would suggest you start with IT career, get some experience, complete a management course such as MBA and then switch to management. This will get you good opportunities and salary.
Know what's better than IT and non-IT jobs? Government jobs!
