NOC and real experience

Dears, have a nice day
This is my first question here i hope i could find a clear answer with some details
I’m asking about the differences between the NOC and the real career experience
I mean Like if i have been graduated from Veterinary Medicine, but i have a 7 years experience in sales and marketing,
What should i do?
What is the best way to get the highest score from those 2 points Noc and work experience.

NOC has to be selected for what you worked on and does not depend on what education you have. So when selecting the NOC, look up for the sales and marketing one.
