I want to pursue my MBA from FMS Delhi. How can I do my specialization in marketing? Do I need to have prior work experience to lap up a high paying marketing job?

Although prior work experience is not necessary to get a job after an MBA, it is desirable to recruiters. If you have work experience, then it will provide you with a little edge over the fresher crowd. If you don’t have then, it is totally fine. Many recruiters prefer fresher over a work experience person. 

To do specialization in marketing, you have to complete your college first; then only you will be eligible to take specialization. Institutes do offer a choice to the students to opt for their desirable subjects, but the catch is the institute cannot provide all the subjects to all the students. There must be competition among the students to opt for trendy subjects. To get ahead of others, you must have to score well in your first year.
