Matches my experience. 2 page resume is standard for senior careers, everything below should be 1 page. The reason is simple: I'm evaluating if you are able to summarize the most important points for how you're fitting into this role into a very limited space. This is a important skill that transfers to many other areas and isn't obvious just by looking at the extensive list of your degrees and job positions. I trashed applications for the sole reason when i felt that the applicant missed the whole point of why i'm reading their resume. Yet some hiring folks may prefer it the other way around so it's also a cultural fit filter in some way.
