Is having a job that you love an advantage or disadvantage when applying for a Masters?
If it is a full time master, I strongly advise you against having a job, especially a full-time one, at the same time. I don't know what the degree you're applying for looks like, but a master's course is usually pretty demanding and requires a lot of personal work. By pursuing two full-time activities at the same time, I think you put both of them at risk.
