Are you using the same resume template from when you finished school or uni, which you hastily update each time you apply for a job? You wouldn't be the only one.
Most people haven't had their CV professionally reviewed for a very long time, if ever. And this could be a problem, as times have changed, and what was considered professional ten years ago will not cut it in 2018.
DON'T put in a personal details section. In particular, leave out your date of birth (unless you are an actor), marital status, and address. Listing your address listed may result in unintentional bias from the employer/recruiter.
DO list your mobile number, email address and LinkedIn profile web link. I like to have these items on the front page header with my name, then as the footer on subsequent pages.
DON'T put a 'career objective' at the top of your CV. The employer wants to know who you are, not where you want to be in 5 years. And they probably assume you want the job if you are applying for it!
DO have a killer 'professional profile' at the top of your CV, which clearly conveys who you are (your skills, attributes and experience) and make sure you tailor it to the job.
DON'T use crazy fonts and colours, and don't include a photo unless you work in the more creative fields. Avoid underlining and italics.
DO keep your documents simple and easy to read, with consistent fonts and sizes (not too small!) and a plain colour scheme. Use bullet points to summarise your key responsibilities and achievements. Use bold for headings.
DON'T list every single job you've ever had and the detailed responsibilities - unless you are a school leaver and haven't had many jobs.
DO put more detail into your most recent and the most relevant previous roles and just provide a summary of other roles. Keep your CV under 4 pages.
DON'T submit a generic CV. It shows you have put in no effort.
DO tailor your CV for each job application, particularly the professional profile section.
DON'T submit a CV with spelling and grammatical errors.
DO ensure you triple check all your job application documents for spelling, grammar and formatting, and ask a friend to check them before submission.
