Why? Do you only have one outfit? No, you have outfits for work, for fun, for play. Have the same mindset with your CV.
I personally have 3 CVs:
- The LinkedIn CV that shows off what I want others to know about me.
- The tailored CV that I would adjust for each job I applied for.
- The detailed CV for HR when they want to know all my work history
For that second CV, do take your time to adjust your CV to each job you apply for. Think about what the employer says in their job description, what you know about the company in general.
The goal is to make sure your CV speaks to their needs and aspirations, as much as your experience and ability.
