Overall Oliver has a very strong resume and he is sure to get a new position as an advertising creator, but as always there are things to improve on. Lets go through this example CV together!
Oliver's summary is well written, but it is too short. Remember that the summary is the single most important section of your CV (learn more about the summary section here).
There is nothing wrong with what Oliver has written in his summary, but personally I would like to know more about him as an employee.
As an example, Oliver could expand his summary to something like this:
As an experienced advertising creator, I excel in developing effective campaigns across multiple mediums. I bring ideas to life and deliver results for clients, consistently producing exceptional results within budget and time constraints.
Collaboration is one of my strengths, and I work closely with writers and designers to produce engaging content. My skills and experience make me an ideal candidate to help your company succeed in today's competitive marketplace.
It is a good list of skills that Oliver has provided, but a small detail which would improve the resume is to add a couple more skills. This will make the skills section look a bit more substantial. As it is now, with only one and a half line, it looks a bit sparse (see above). Note that a differnt resume template could also be an option for making the skills list look more extensive (read more about choosing the right template here)
A second point to make is that if Oliver wants to have the skills section before the experience section, then he should make sure that this section looks perfect. Personally I prefer to have the skills section further down on the CV, but that is subjective.
The work-experience section is what I love the most about Oliver's resume. It shows what he has worked on and what his strengths are. This part shows confidence.
The astute reader will of course have seen that the wordings of the description of Oliver's current job is not perfect. "Develop and implement..." sounds a bit rigid. But do you know what? The recruiter will not care that much. The most important thing is to convey your story to the recruiter.
The education section is not the most important part for Oliver's resume, since he has good work experience. As such it is good that he has placed the education section far down on his CV.
Note that Oliver has added an interesting experience to his education description:
Served as a member of the Ad Team, participating in the development and execution of a comprehensive advertising campaign for a major brand."
Some companies treat such an experience from University as a clear advantage. Maybe this means that they are willing to give Oliver an even higher salary?
Normally I do not promote the references section of the resume, but for Oliver I will make an exception. For Oliver I see an opportunity in having some of his old clients as references.
Adding some previous clients as references would send a very clear signal: Oliver is extremely good at what he does, just ask his clients.
