When you apply, always include a CV and a covering letter and we also urge you to attach relevant supporting documents such as Transcript of Records.
Your CV should include a thorough overview of yourself and information such as your contact details, education, employment history, and also your skills and experiences. And remember that you do not need to squeeze everything onto a single page.
In the covering letter take the opportunity to highlight your relevant skills, strengths and motivation for applying and emphasize to us why you are the right candidate for the job. Be precise and prioritize your information as the covering letter should not exceed 1-1½ pages.
