It's not sufficient to make 1% more money. If it's not a 20%+ increase, you might as well bide your time. This means the first, lower paying job, is sticky. Otherwise you could leave instantly at every better offer without penalty to long term prospects.

And even for those brilliant people who can get it on the first try, you're taking about 2 months minimum to go through the interview process. If you're someone who doesn't like taking risks, that's a tall order until you've become convinced there is no path to promotion within your company.
