BCA graduates are employed by small and medium size IT and ITES companies. In addition, business enterprise hires BCA graduates in their IT Departments and computer operations.
Large IT companies employ BCA graduates only in production or apps support roles. Employment opportunities for BCA graduates are less until they do a post-graduation degree such as MCA.

BCA is degree course and it is a better and higher qualification in comparison with Diploma in Computer Science from a Polytechnic.
It will provide you better job opportunities and also it will help you with work visa when you get international assignments.

Dear Sai,
As there is more demand of software engineer, I would suggest you do B.Tech. There is more demand for B.Tech graduates and after doing engineering you will have more job opportunities rather than after doing BCA. The second thing, it is only software engineers who get high salary packages.

You must complete additional certificate courses:
JAVA, Python, Web Programming and Software testing.

Check for Techno India Institute. Check the below link for more-

Both central and state governments do not fill their IT vacancies by campus recruitment. You will have to apply against open and advertised posts by competing with all types of candidates to get government job.

Yes, B.Ed can be pursued after completion of any graduation program. Fee will depend on the college and mode that you opt for.

You can seek Admission in PG provided you are able to clear your back log before the cut off date of submission of documents which varies in each university.

BCA is a basic degree and is not accepted by IT industry for development job by large MNCs. Even if you are able to get job in large MNCs, it will be a support role in lower cadre. You are advised to plan your education minimum up to MCA for a meaningful career.
