Ph.D

If college will fund your stipend for your Ph.D, it would be a better option. If not, it will take a long time to get out of this course and to find jobs either in the education field or in any other field. No company will recruit Ph.D graduates directly at the initial level because of the fact that they need to pay a higher amount for the same job that would be done by a UG student. Please select carefully. Only if they provide stipend during your Ph.D then opt for the same.
All the very best.

VIT Vellore should be preferred over SRM since VIT has must better affiliation to the foreign colleges and you will be benefited much better for your foreign education.

No, it will not be advisable. Regular MBA demands your complete time and attention. You will be required to clock almost 10 hours at college and pursuing PhD along with it will not do justice to either of the courses.

There is no number of specific years which are defined for this. I would like to say that Ph.D is a course which required 20-30 original papers to be published after that your Ph.D gets over.
All the best.

Hi Milan,
You have to be proactively searching for universities offering research work in your area. Check their research activities, noble prize winners, patents, publications etc and overall ranking. Admission process includes an acceptance by a research supervisor. Before a formal application process, you must communicate with the specific department supervisors and share your research ideas and proposals. They have to accept you before you submit your application. Enquire about funding, stipends etc before applying. Also take the GRE .
