Resume, Cover Letter - Introduction Letter Examples

[Ideas]

This is the part I really don't understand, why would they do that, or how would they "get to know" the applicant?
Usually for me, I have two pages for the resume and one page for the cover letter, so that's 3 in total at least...

They prefer people who only had 1-2 jobs in the past many years. It is definitely easier to do a 1 page if you were more stable with employment. But I saw someone with a lot of impressive stuff who condensed his into 1 page.
