Keep an eye on words which cannot be supported. If you call yourself an excellent team leader, how does a hiring manager know it is a statement of truth?
Don't call yourself a very good team player, or don't say you have excellent marketing skills. They are high sounding empty words only. Describe your abilities and skill set and let the hiring manager decide their worth. You cannot give yourself a certificate.
Avoid certain words that indicate common traits. You say you are a good worker. Which manager wants to have a bad worker? Such words sound empty.
Instead of beating around the bush, tell recruiters and hiring managers what you can do on the job.
With the following words you can catch the attention of hiring managers:
Created, increased, raised, reduced, improved, developed, accomplished, won, on-time under-budget
You should have action words on your resume. Verbs project your image by highlighting your capabilities and background. Hiring managers clearly understand what you did in the past and what you can to do in their company.
Supposing you are hiring someone, whom do you prefer? Do you want to take a man who says he has excellent managerial skills or the one who says that he increased the production by 5 percent when he was the manager in so and so company? The choice is obvious. So your resume should be clear cut.
It is expected of you to use nouns and verbs common to your industry or your professional field. Words like 'on-time' and 'under-budget' brighten your chances of getting the job.
