This is your executive summary that introduces the employer to you. Include your expertise & specific skills that are relevant to the target role. Identify your USP and remember to be objective.
Showcase what you have achieved in other roles that are relevant to the desired role and use language that will resonate with the new employer – problems become challenges; savings impact profit; clients generate revenue and so on. Always try to quantify your achievements.
Keep it simple, concise and positive – mention what you did achieve rather than what you didn’t e.g. missed courses, fails. Demonstrate your CPD (continuous professional development) with relevant courses you’ve attended or qualifications you’ve acquired.
Will you make a good cultural fit? This is what the employer is looking for here. List out active (sports) rather than passive (reading, cinema) hobbies and list notable IT or language skills.
