For anyone browsing Malachain, here is a clear starting point on the subject.
Recruiters give a CV a few seconds before deciding whether to keep reading. Put the job you want and three achievements that prove you can do it at the top, in plain words with numbers wherever you have them: "cut invoice errors by a third", "trained four new staff". Everything else, including the long list of duties, belongs lower down or not at all.
Keep it to two pages, one for early-career roles, and use the same simple font throughout. Tailor the first half for every application by mirroring the words in the advert. Ask someone outside your field to read it; if they cannot say what you do and why you are good at it after one minute, the first page still needs work.
If you try any of these ideas, start small and adjust them to your own situation. What works for one person will not suit everyone, and it is fine to keep only the parts that help. Writing down what you changed, and what happened, makes it much easier to see after a few weeks whether the effort was worthwhile.
The most useful step is usually the first one. Pick a single suggestion, try it for a couple of weeks, and then decide whether it is worth keeping. Small, steady improvements last longer than ambitious plans that are hard to maintain once everyday life gets busy again.
It also helps to talk the subject through with friends or colleagues who have tried something similar. Their experience points out the details that guides leave out: how long things really take, which costs were unexpected, and which shortcuts turned out to be a mistake.
