Questions and answers
How many CVs do you need?
For most jobseekers, one CV is enough. However, when you apply for a job, you need to make sure that the information in your CV matches the job requirements. This means you may need to amend the order of your skills/experience or modify your profile to suit the job you're applying for. But, if you are applying for several jobs and the requirements for each are very different, it's better to create different CVs. An example of this would be if you wanted to change career direction but still wanted to keep your options open by applying for jobs that matched your professional experience.
Which CV format should you choose?
It all depends on your experience and what you want to do next. Choose the format that will portray you most accurately and the one that will highlight relevant experience.
