This system is stupid,
I have over 15 months of experience in NOC B category, I worked as a Banquet Supervisor for 8 months, F & B Supervisor for 3 months, Front desk Supervisor for 7 months. they still don't consider it, although having different positions at several places each positions i changed gradually responsibilities increased, I earn better position but NOC Code different for each positions i worked, so i am not eligible for express entry as per their rule.
It means even though you are getting promotion you can't take better position bcz than your noc code differ.
