Career history: Focus on the most recent, most senior and most relevant aspects in your career. Don’t waste space on minor skills and repetitions from the past.
Your CV is a tool to sell your skills, more importantly what you can offer a potential employer.
Showcase assets that make you a strong candidate: this can be knowledge, experience, results, and opinions about your performance, character or working methods.
Highlight your achievements and key project experience.
Check for mistakes. Nothing worse than typos and errors on a CV.
Leave the employer wanting more. Details are important, but don’t give away too much and leave plenty for the employer to ask in the interview. This way you can set up the questions they are going to ask and give yourself time to prepare some strong answers.
