求教博主，在同一职位大类下的不同小类能算作是相同专业吗？

比如说在anzsco的MINOR GROUP 312 BUILDING AND ENGINEERING TECHNICIANS大类下面有
          UNIT GROUP 3121 Architectural, Building and Surveying Technicians
          UNIT GROUP 3122 Civil Engineering Draftspersons and Technicians
          UNIT GROUP 3123 Electrical Engineering Draftspersons and Technicians
          UNIT GROUP 3124 Electronic Engineering Draftspersons and Technicians
          UNIT GROUP 3125 Mechanical Engineering Draftspersons and Technicians
          UNIT GROUP 3126 Safety Inspectors
          UNIT GROUP 3129 Other Building and Engineering Technicians
那么这下面的这几个小类是不是都是专业相关呢？本人学的是电气的，有建筑设计院建筑电气设计的工作经验，在这边找到的是建筑设计的工作，想以此申请工签和pr。不知这样算不算专业对口？是否可以有学历和工作经验的加分？谢谢。
