Hi Rakesh,
Top ones like Mannheim and WHU Otto Beisheim Business Schools require very good grades, high GMAT scores and work experience of may be 2 to 3 years. Different B-schools may have slightly flexible requirement which you must check on their websites.

There is no specific policy on gap years at German universities. Selection in German Universities is based on your overall academic performance. If you have any gap years in your studies you must have good reasons to explain in interviews if asked by interviewer.

USA is the best without a doubt. Canada and Australia are also preferred in terms of affordability, RnD and job opportunities.

Not recommended Jugal, German universities accept highly academic students.

You have an option of scholarships as you are going for Masters course. Both of these countries have their own specializations depending on which course you are opting for.

Can you please tell what exactly do you want to do because your experience indicates that you should go for MBA in retail management, supply chain management and logistics and distribution, etc. There is no link between your work experience and MS course. So, I am providing you the link where you can get a clear idea about the profile of purchasing manager:

It entirely depends on your skills and academic grades. Apart from these, your internship/project work, research work, prior work experience and additional skills will be influential.
