They seem to want both. Application form so they can filter you, then a CV for the interviewer to have Infront of them in the interview(s)

Doing the work to update your CV means you can mostly copy/paste segments into the forms though.

(Knowledge more from tech job hunting - unsure about other industries)

Ah mate it does my fucking head in.

Upload the CV and then fill out a form with pretty much the same info on the CV.

I use Glassdoor for applying jobs in the down season - I work building bars at festivals in the UK so most of the new work I bag is word of mouth, and usually March - Sept.

During the off, I just use Glassdoor and the 'quick apply' option.

Bearing in mind this is glassdoor.es so I'm not sure if the UK one has a different format? 

Depends on your field as well

Best advice I had, was to rewrite the job advert as your CV... so each application will be different.

Obviously don't lie about your experience, but if they're wanting a "dynamic self-starting highly motivated..." then, well, that's what you are.

Now, whether that forms a CV or an online form, it doesn't really matter as you'll be just copy & pasting their advert anyway.
