I have been selling for a year, and now I want to do mechanical design. Now you need recruitment experience, you can find it.

1. Find a local school that trains CAD or mechanical design and take short-term classes. Because such training schools generally have company resources, you will be more likely to get close to industries and occupations.

2. Submit your resume according to common sense and attend job fairs. Your resume needs to highlight your "skills" in mechanical design, and you need to tell the enterprise that "one year's sales work has made you understand the job responsibilities of each position in the company. Through self-reflection, you have positioned your career in mechanical design, and you are willing to start with the most basic work."

Good luck!
