I spent ages working on my CV (made redundant at 56) but I have found very little use for it as most companies seem to have their own recruitment systems that want you to input directly into them. Job applications often consist of a series of annoying questions (x 10, max 500 words per question) like 'What do you think makes for great Leadership and outline examples of where you have shown it in the past, in relation to this job application?'
Years ago, Employers would be satisfied with just looking over your CV to see the kind of work that you'd done, and a short covering letter explaining your interest in the job.
A friend of mine told me that these databases often make initial auto selections based on the wording in the job advert so everything needs to be rewritten to include as many of these 'buzz words' as you can.
