HiYou need to find your exact job within this list https://www.canada.ca/en/immigration-refugees-citizenship/services/immigrate-canada/express-entry/eligibility/find-national-occupation-code.html#find
Then it will tell you what category it comes under A or B, if you select the incorrect category it will cause problems at IRCC as they asses your job with absolutely scrutiny for the noc level you have selected. Your PR application could be denied. If you don’t mind me asking what is your career?
I am operational risk analyst which is a Noc 4162 - Type A.
I'm planning to apply under High-Skilled Workers - Atlantic Immigration Pilot program but not sure about if I can do it with a noc type B job offer (Administrative Assistant - Noc 1241)
Thanks
