How many times do you get to make a first impression?
The answer of course is 'once': so make it count.
The first impression you make on an employer is through your resume and as such it should highlight your employment history, qualifications, skills achievements and personality.
How professionally your resume looks will make a difference in getting short-listed for a position.
Indeed a strong resume can itself secure you a job, especially if you are applying for temporary work. A poorly constructed resume can give a potential employer a negative impression of you and prevent you from securing an interview.
