Earlier quoted context omitted.
You're focused on the wrong thing. The resume comes way too late in the job acquisition process to really matter. The vast majority of jobs are filled through networking, not applying cold with a great resume. You need to work on meeting people in your field, at the companies where you want to work. It's not what you know, it's who you know. Go out to meetups. Be a friendly, helpful person. Make friends, lots of them…
I still doubt the "networking" part. I've got my first job in the states because a recruiter called me. Same for the second job. The third one was through being acquired. The fourth one, you could call networking if you call showing up for a recruiting event networking. 5th one? You guessed it, recruiter called. Sixth one? Yep. Exactly. Before that, I worked in Germany. 1st job, applied cold. Second one, applied cold…
When I hire the first thing I do is also reach out to my personal network to see if anyone is looking for work or know anyone who is.
My wife did just manage to land a job with a cold application, though, so it's not like either way doesn't work.
