Resume best practices
Tailor Your Resume for a Mainframe Developer
Customize your resume for the specific position you're applying for. Use keywords from the job description and highlight the most relevant experience.
Keep It Concise and Focused
Ideally, your resume should be one page (two if you have extensive experience). Focus on achievements and essential information and avoid fluff.
Use a Clean, Professional Format
Stick to a simple layout with consistent font, spacing, and section headings. Use bullet points for readability. Avoid overly decorative fonts or colors.
Start with a Strong Summary
Write a compelling summary or objective at the top that briefly outlines your background, key skills, and what you bring to being a Mainframe Developer.
Emphasize Achievements Over Duties
Use bullet points to describe what you accomplished as a Mainframe Developer, not just what you were responsible for. Include measurable results when possible (e.g., "Increased sales by 25% in six months").
Use Action Verbs
Start bullet points with strong action verbs like "Led," "Developed," "Improved," "Streamlined," to convey impact and ownership.
Highlight Skills and Tools
Create a dedicated skills section that includes technical tools, software, or soft skills relevant to being a Mainframe Developer (e.g., Excel, Python, CRM systems, leadership, communication).
Include Education and Certifications
List your educational background and any relevant certifications or ongoing courses. Mention GPA if it’s strong (generally above 3.5) and you're early in your career.
Proofread Carefully
Avoid spelling or grammatical errors since they can be deal-breakers. Ask someone else to review your resume or use tools like Grammarly.
