I am about to complete Computer Science, as I am in final year with 77% marks. I was selected by HCL team but package is too low .

It appears that you got selected in HCL's BPO arm, otherwise HCL Technology offers a package of Rs. 3.2 Lac PA which is at par with any MNC company for a fresher B.E. candidate. If you got selected in the later, I would suggest you to join and work for few years before you try to be an entrepreneur.

Dear student, It is of much encouragement that you like to start your own business instead of doing job in your studied domain. But here I just add one thing --- i.e to be careful for choosing time to start business. I think first join the job you have been offered or any job likely to be offered .
