Answer these five questions before you send a resume.
1. Which role are you after?
Sales, service, clinical application and trade each want a different resume. One generic resume for all of them is usually good for none.
2. Devices and brands you know
If you worked with a device at university or in an internship, name it. That is far stronger than 'I am interested'.
3. One concrete sample
A project, an internship report or even a small market analysis beats a list of courses.
4. City and travel readiness
For sales and service roles, where you live and whether you can travel matters. Say it plainly.
5. A tidy file
PDF, a clear file name, two pages at most.
