It depends on your interest. the difference is not really huge.



CSE: computer science engineering is involved in many aspects of computing, from the design of individual microprocessors, personal computers and supercomputers to circuit designing and writing software that powers them.



IT: Information Technology deals with the use of electronic computers and computer software to store, protect process, transmit and securely retrieve data. IT professionals perform a variety of tasks that range from installing applications to designing complex computer networks and information databases.



The major  difference between both these field is that IT deals with the application of computing technology to real life processes, while, Computer Science deals with the science that facilitates these applications.



Career scope:

Job openings for CSE graduate is much higher in the corporate sector. you can join as junior programmer, database administrator, junior network manager, Data Analyst, Software Developer, Software Engineer, and Client-Server Systems Manager etc in the initial stage.
