I am trying to provide answers serially:-
(a)What is a role of BBA candidate in a company?
Ans:- Initially a fresh BBA has to work in an assisting role in Administration,Co-ordination, Sales, Marketing, etc. under an experienced MBA.
(b) After doing BBA what kind of job I can get?
It entirely depends upon the company you join, its business, vacant position against which you are appointed, its area of expansion, etc. No specific comments can be made in this regard. You have to assist the team leader who would be an experienced MBA.
(c)Which companies take BBA students?
Medium and smaller companies in every domain take BBA students.
(d) What is the Salary package and increments in this job?
The salary package depends on the job profile, size of the company and the place of your posting. It also depends upon economic environment at that point of time. I feel that a fresh BBA can't expect more than Rs. 20,000/- p.m at the present juncture anywhere in India.
(e) Is Techno India Kolkata is good for BBA?
Check the Website of the company for detailed information. However, adjusting in the work environment of a company does not always depend upon the company alone. I have seen many people couldn't adjust in bigger IT companies like Infosys, but rose in stature in smaller companies.
