Still waiting to hear back from all those jobs you've applied for?

Even if you have spent hours spell-checking, organizing, and editing your résumé, there still might not be a guarantee that you'll get a callback if your résumé is missing one crucial thing. And according to former Google HR boss Laszlo Bock, that crucial thing is this: specificity.

When he served as senior vice president of people operations at Google, Bock saw his fair share of résumés, with Google being one of the most sought after--and competitive--employers today. His role in HR naturally allowed him to gain key insight and perspective on what makes a stand-out résumé. In a LinkedIn post, Bock wrote about the importance of measuring your past work in order to differentiate your accomplishments from other applicants:

"The sole purpose of a résumé," Bock wrote, "is to get you past that first screen and into an interview." And in order to get past that first screen, you need to draw in hiring managers by properly highlighting your past work.

Luckily, Bock shares a simple formula you can use in order to make your accomplishments stand out. Each accomplishment you list on a résumé should be presented like this:

Accomplished [X] as measured by [Y] by doing [Z]

Explains Bock, "start with an active verb, numerically measure what you accomplished, provide a baseline for comparison, and detail what you did to achieve your goal."

When you explain how you arrived at an accomplishment, employers will gain insight into your strengths and consider you as more credible.

Achieved annual business plan commitments for volumes, model mix, wholesale revenue, selling expenses, and brand.

However, according to Laszlo Bock, it is much more effective to share achievements in a format like this:

As a team member, contributed to 21% increase in advertiser spend by achieving 158% of target number of customer contacts (80 contacts per week) and 192% of target interaction depth (20 minutes per customer).

Which version do you think would impress a potential employer more and spark a desire to learn more in an interview?

Measuring your work and providing real data may sound like a daunting task at first, but it's an important move to make if you want to impress recruiters and land that job.

And that's what we all want, right?
