Most companies use software to scan resumes for keywords. To pass, use standard headings (like 'Experience' and 'Education') and avoid putting important info in headers or footers which robots sometimes miss.
Instead of saying 'Responsible for,' use strong words like 'Spearheaded,' 'Developed,' or 'Optimized.' This makes your achievements sound more impactful to hiring managers.
Don't just list tasks. Use numbers. Instead of 'Increased sales,' try 'Increased sales by 25% over 6 months through a new lead generation strategy.'
