A functional CV is the best way forward for many people. Particularly since most people do have a variety of jobs and a chequered career to some degree.
As opposed to in inventory CV, or even what most people describe as a chronological CV, a functional CV, on the other hand doesn't necessarily list each and every one of your jobs, nor does it necessarily list them in strict chronological order.Functional CVs give you more scope, flexibility and leeway to summarise your experience and sell your skills in a more concise and sometimes more appealing manner than typically more rigid chronological formats allow.
