For an employee, a resume is more like an advertisement poster that is trying to sell its best features to the person willing to pay for such services.
So crafting a great resume, using the right kind of etiquette should your main focus because HR recruiters and managers receive resumes by the tens of thousands and up to a hundred applications for a single job opportunity! This means that an HR manger would probably spend no more than three minutes to review a single resume, which basically means that you have three minutes to sell yourself before your resume is discarded into some deep dark corner of the office.
Now, a well drafted resume is one that speaks for its owner. It is a clear, concise and authentic summary of an individual’s past achievements, their current satiation and their future potential.
The most common mistake that people make when drafting a resume is that they assume they can use one resume to apply for any job. The best made resumes are tailored according to the job and even company that it applies to. Other, more obvious etiquettes include using a professional and classy font that the HR will appreciate reading.
