When Maria Reyes saw a job posting that felt like it was made for her, her instinct was to hit reply immediately. But then she hesitated. "I always thought, if I respond too fast, they'll think I'm desperate," said Reyes, a marketing coordinator in Phoenix. "So I'd wait a day or two, maybe even three."
New research suggests Reyes—and millions of job seekers like her—have been letting go of opportunities for no good reason. A study published in Management Science by researchers at UC San Diego, George Mason University, Vanderbilt University, and Cornell University found that faster job applicants actually get hired more often, not less.
The researchers analyzed 11.6 million real-world interactions on Fiverr, a platform connecting employers with freelancers, and conducted a series of experiments involving more than 8,600 participants. The results were striking: a one-hour delay in responding reduced hiring likelihood by 46 percent, while waiting a full day cut the odds by roughly 90 percent. The effect held even when employers could see resumes, ratings, and the actual content of responses.
"People have this intuition that playing hard to get is somehow useful," said On Amir, a professor at the UC San Diego Rady School of Management and co-author of the study. "We find the opposite is true."
The experiments revealed why speed carries such weight. Faster responders made stronger first impressions—participants judged them to be warmer, more competent, and more likely to be responsive in the future. Essentially, people use reply speed as a window into what someone might be like to work with.
"Speed is a signal," said co-author Einav Hart of George Mason University. "People see a quick response as a sign that you'll be attentive to their needs in the future, not just right now."
The researchers also uncovered a telling gap between what people said and what they actually did. Survey participants claimed same-day responses would be perfectly acceptable—yet when it came time to make actual hiring decisions, they consistently favored those who replied within minutes.
The findings carry an important caveat: speed alone isn't enough. The researchers cautioned against interpreting the results as a license to fire off generic responses the moment an opportunity appears. Authenticity matters too. In the experiments, the appeal of fast replies faded when recipients suspected the responses were automated or generated by AI. A quick reply works best when it also feels genuine and personalized.
For job seekers nervous about appearing too eager, the takeaway is simple: when the right opportunity comes, there's no benefit to making someone wait.
"People worry about seeming desperate if they respond quickly," Amir said. "But responding quickly signals that you're engaged and attentive. That's exactly what employers are looking for."
