Did you confirm that by looking at the job duties and responsibilities? You should not choose an NOC based on job title, you have to choose based on job duties and responsibilities (as well as the lead statement).
For example, NOC 0621 may show "assistant manager" as a title, but the job duties are:
- Plan, direct and evaluate the operations of establishments engaged in wholesale and retail sales or of departments in such establishments
- Manage staff and assign duties
- Study market research and trends to determine consumer demand, potential sales volumes and effect of competitors' operations on sales
- Determine merchandise and services to be sold, and implement price and credit policies
- Source and negotiate with vendors when necessary to procure merchandise for resale
- Develop and implement marketing strategies
- Plan budgets, authorize expenditures, and monitor revenues
- Evaluate and improve customer service and respond to customer requests and issues
- Address staffing requirements, including the hiring, development and retention of staff
For example, a lot of people who initially choose NOC 0621 based on job title have nothing to do with planning budgets, hiring staff, conducting research or planning strategies. Their job duties better correspond with 6211.
