1、我在國內本科畢業 第一份工作的title是Trainee，一週40個小時，做了1年又1個月，其實是做客服和銷售的工作。

Job duties and responsibilities 是：perform sales order management tasks and process customer inquiries; maintain customer relationships through proactive communication related to order management; liaise and support Logistics team with the delivery of products from the plant or third party warehouses; support credit management, billing and accounts receivable follow-up; develop potential customers; deal with customer complaints, etc.

感覺這個比較符合這個Code，但是是C類，一點用都沒有：
6411 C類 Sales and account representatives-wholesale trade (non-technical)

請問結合工作性質描述，可以寫這個code麽：
6221 B Technical sales specialists-wholesale trade

2、我研究生畢業的第一份工作是industrial engineer， 這個就是2141 - Industrial and Manufacturing Engineers，符合A類的要求。但是是一週30個小時，但工作證明上的工資不低，請問這個可以給到我加分麽？感恩！
