Hi,

This depends on what your interest is. Since you have chosen Computer Applications - You could opt for a job in the IT sector and then do your post graduation - MCA. The reason is someone with experience + MCA has better chances for placements as compared to a fresher.

As far as I see ideally IT sector is one option unless you wish to change your field and opt for something else. You could look at jobs in the defence sector, civil services also if you wish to. There are teaching jobs. You could look at that too. 

Let us know what your interests are so we can get back with better information.
