I never stated that "most employers prefer candidates with Master degrees."
What I did state is that "...many employers realize this value and will make it important in their search."
I am from India (Bangalore) and here every company is asking MCA(Master of Computer Application) or any master degree for development job.
What differences will be their between Master degree holders and graduates?.
There would be many differences as graduate degree programs contain additional activities, knowledge areas, workshops, processes, advanced thinking, thought leadership, etc. that are not included in undergraduate degree programs.
