Whether you should include technical jargon in your CV depends on the specific job you’re applying for, as well as the employer and the industry they operate in. If you’re applying for a position that requires highly developed technical skills then including relevant jargon can serve to demonstrate your qualifications and familiarity with the field.
Let’s say you’re pursuing a software developer position at a company that develops fintech apps. The employer will likely be excited to read about familiarity with Spring or Hibernate frameworks or your skill at integrating APIs.
However, if this knowledge isn’t directly related to the open position or employer, it’ll confuse the employer and may dissuade them from reading further.
When writing about skills or achievements that the employer might not be familiar with, focus on using language that is clear and easy to understand.
