One CV per job, not one for all of them
The most common mistake in job hunting is also the most comfortable one: one file, sent thirty times. The result is predictable. A CV meant to fit everything fits nothing particularly well — and when two hundred applications sit on one opening, what decides is not your best sentence but a first twenty-second glance.
The posting tells you what matters
Every job ad says what the employer is looking for, often quite literally. Someone who writes "invoice verification" wants to read "invoice verification", not "commercial duties". This is not a trick and not keyword stuffing: it is the plain decision to call the same thing by the same name as the person reading.
That is what the job-ad match in the editor is for. You paste the text of the posting and you see which terms carry it and which of those appear in your CV. The terms come from the ad itself, not from a list somebody last updated three years ago.
What you actually change
Not everything. Three things usually do it:
The order of the bullets. Whatever fits the role belongs first under each job. The rest moves down or goes.
The wording. Swap your phrasing for the ad's phrasing wherever both mean the same thing. Where they don't mean the same thing: leave yours. Claiming something you can't do holds up exactly until the interview.
What can go. The side job from 2016 doesn't need to be in every version. The space belongs to what counts.
One CV per role, not per evening
That sounds like work because it used to be work. In CVgogo you duplicate an existing version, change the three things above and download a new PDF — for most roles that's a few minutes. Give the versions names you'll still understand in a month: not "CV final 3", but the employer's name.
And keep one complete master version that all the others come from. It isn't meant to be sent; it's your archive — everything you have ever done, at full length. Cutting is easy at any time. Remembering which month the internship started gets harder every year.
