May I have to customise my resume to matching each job roles or to be honest to expose my 20 years experiences?

Hello! I think that the key to creating an effective resume is finding a balance between tailoring it for specific job roles and showcasing your impressive 20 years of experience.

Here are some suggestions:

1. Tailor for each role: While you don't need to rewrite your resume from scratch, it's important to adjust it to highlight the skills and experiences most relevant to the specific job you're applying for. This shows employers that you're focused and understand the role's requirements.
2. Showcase your 20 years of experience strategically: Your extensive experience is an asset! Focus on the parts that align most closely with the job you're targeting. You can group older or less relevant experience under a section like "Additional Experience" to keep the focus on recent, applicable roles.
3. Use a hybrid approach: Start with a strong summary or profile at the top of your resume that highlights your key achievements and transferable skills. Then tailor the details of specific roles to the job at hand.
4. Be honest and concise: Honesty is vital, but that doesn't mean you need to include every detail of your career. Emphasize the most impactful and relevant aspects to make your application stand out.

Hope this helps!
