1. This is the professional age. It's no big deal to write your resume separately and print more copies.

2. If you write two, it depends on what position you are applying for. For example, if you apply for a manager, if you have both management experience and technical experience, then you can write two positions.

If it is a single position, it is best to have a major in this field and can write or apply, otherwise it will be separated.

The above hope can help you, thank you!
