But there is a LOT of conflicting advice. I like to think my CV isn't a "straight in the bin" job but I've been told:
A) Only list relevant experience. B) List everything so you have no gaps.
A) Bullet point your work experience. B) paragraph it
A) describe what you did B) dont describe the job, they know what a barmaid is...describe what you gained.
A) put in your hobbies B) dont put in your hobbies
A) put your work experience first. B) put your education first
A) write in the first person B) write in the third person.
A) Black only no style B) have a little character - stand out.
The list goes on...what are you meant to do?
Not sure if you're still on the thread but for what it's worth, what I do with my clients:
For junior candidates/people with limited experience, everything goes in and I do my damnedest to make it relevant to the job they're going for (you get good at this bit as a CV writer!). Everyone else gets most recent things in detail and earlier stuff listed by job title only under "Earlier Roles". (There will be some people with complex career trajectories who need functional/skills-based CVs but this is unusual.)
Bullets/paras - both could work, but it needs to be readable. No one's going to wade through huge blocks of text or dozens of bullets.
"Describe what you did" - you need to make it relevant to the advertised role. So if you're an ex-barmaid looking for work as a bookkeeper you ought to emphasise cashing up, inventory, things that demonstrate attention to detail and other relevant skills.
Hobbies - I'm not sure it makes a difference beyond graduate level (where the play football = teamwork thing does seem to sway some recruiters). Personally I think if you're going to write "Cooking, travelling and spending time with family" you'd do better to just leave it off - boring and generic. The only exception is for relevance - so if you're an Eagle Scout and are applying for a job with kids, for example.
Work experience or education first - it's really not a deal breaker. I tend to put education at the end except for recent grads.
First/third person - as long as it sounds clear and direct either is fine. If first person I tend to omit "I", otherwise it starts every sentence.
Black only/not - it depends on the role, level of seniority etc. Though I have to say that if you don't have a good eye for visual design then black only is safer (have seen some shockers).
There are a lot of variables, and lots of approaches that are perfectly fine if applied consistently.
