Study Abroad

There is nothing such called conventional or unconventional courses in MBA. There is a core specialisation in HR, Finance, Marketing, Operations, System etc. and there is new specialisation such as retail, healthcare, supply chain, agro-business.
You should pursue on the basis of:
Location: Even if you do from IIM, XLRI or tier 0 and tier 1 institute, there will be fewer opportunities globally. Hence if India and middle east or Africa in your mind, do it from India. If US is in your mind, opt top ranked institutes in US
Ranking: Only upto top 50 ranked school to have opted
Passion: What is your passion. I know non Mbas too drawing a good salary, purely due to passion.

An advanced certificate (Considering it as something done from a reputed place as well as after graduation).
The answer that I gave for PG in Advertising Management prospects abroad and in India seems appropriate here:
An M.Sc in advertising management is a very popular-innovative as well as the less taken domain of studying mass media or mass communication. While doing the course, one learns how to see the need, plan, use the USP and create USP of the product in hand. The management of advertising of a particular product is to be done to see the impact. Along with this, the question demands response to career prospects for public relations. Public relations, on the other hand, has similar notions. The jobs that can be done abroad or in India after pursuing an M.Sc advertising management as well as a Public Relations Management degree are:
1. Teaching
2. Research
3. Job in a News Channels
4. Consultancy to get the Advertising Campaign done of a brand
5. Public Relationship Agencies
6. Event Management
7. Counsellor and Trainer
The above profiles can be developed for a job in the Advt. Management space.

A Diploma in Public Relations (Ideally a Post Graduate Diploma) shall help in getting Good Jobs through added Skills of Communication Skills, Interpersonal Skills, Corporate Communication.
Public Relations is much in demand as there are mandatory departments in all multinational companies as well as in small enterprises, even Universities and PSUs have these departments. It is always better to have the academic credential to claim a good job.
The guiding paragraph is as under:
Public Relations Management and Corporate Communication are the rising domains of careers because the corporates are finding it tough to reach the world without skilled professionals who make the best of communication.
The hiring is not just restricted to the offering by the Information and Public Relation Department. Any ministry or department that is dealing with people, has a need for someone with a Master's degree in mass communication/public relations, etc. These jobs are offered for the role of Public Relations Officer and have ample scope for the eligible people.
ABROAD: Corporate Communication and ADV/PR Management is one of the preferred domains in Mass Media abroad. The PR Agencies have lot to do there and have an active role in Media.
