Here's my simple rule of thumb for job seeking: You have ~10 seconds before hiring managers bounce to another candidate or decide to take the next step with you.
"Next step" translates to roughly two things:
a) Spending more than 10 seconds on your resume, portfolio, or LinkedIn.
b) Contacting you directly.
But hold on, is 10 seconds my recommendation for standard operating procedure as recruiters and hiring managers? Of course not. Yet regardless of how much time they actually spend, your most important info should be quickly digestible. Ten seconds or ten hours, don't bury the lede.
Here's how you can use the 10-second rule of thumb to your advantage.
