Hi Luis
Good discussion... I think it really comes down to what sort of job your are applying to. For me, as I contract, I'm trying to highlight my product knowledge and soft skills, and industries (specialize in security so I diversified in industries and components). My resume is a maximum of 5 pages.
It's pretty much page 1: Contact Details, Summary line of my skills, dot points of the SAP components and technology that I have experience in, and then another column of dot points with my non-tech skills (strategy, team leadership, support, project, etc)
The 4 pages cover the contracts/jobs I've held. It's usually 1/3 page per client where I describe the job, deliverables/outcomes and achievements for each. I most cases it's dot points after an introductory sentence.
As I contract, few employers read beyond page 1 if they know who I am. However, I provide the examples, etc so I pass the HR checks and they have sufficient evidence to justify why I was chosen over other candidates.
The challenge (as I mentioned at the beginning) is to target the resume. If I was to apply for a Government contract, I would have to follow their selection criteria process which would entail a completely different resume layout. I'm glad I don't job hunt much and have recruiters and industry people reach out to me directly. As I change job frequently, I don't find it too difficult to keep resume up to date.
