Fast Replies Boost Hiring Likelihood, Study Finds

Reply Fast or Lose the Job? What 11 Million Messages Show

Waiting a few hours to answer a job email might feel like strategy, a way of looking busy or in demand. New research says it’s closer to self-sabotage. A team of business researchers studied more than 11 million real job exchanges and ran several follow-up experiments, and the result kept holding up: a delay of just five to ten minutes can hurt someone’s odds of getting hired. The popular idea that playing hard to get makes a person look more desirable falls apart under the data.

Published in the journal Management Science, the study tracked freelancers responding to job inquiries on the platform Fiverr, then ran separate experiments testing the same idea with caterers, doctors and photographers. Wait more than a day to answer a message, and the odds of landing the job drop by roughly 90%.

That number is jarring given how many job seekers assume the opposite: that a slower, measured reply signals confidence. The data tell a different story. Speed itself sends a signal, separate from how good the message is or a person’s star rating.

Reply Speed Predicted Hiring Across 11 Million Job Exchanges

Lead author Einav Hart of George Mason University and colleagues from Vanderbilt, Cornell and UC San Diego started with Fiverr’s own transaction records. Fiverr is an online platform where businesses hire freelancers for tasks like graphic design, copywriting or voiceover work. The dataset covered 11,666,355 exchanges between buyers and sellers from December 2022 through December 2024, tracking exactly how many minutes passed before a freelancer answered a client’s first message, and whether that conversation turned into a paid job.

Results were steady: reply within a minute, and the odds looked best. The longer the wait stretched, even by minutes, the worse those odds got, with the sharpest drop-off once a reply took longer than a day.

To make sure this wasn’t just one quirky platform, researchers ran three more experiments with over 3,600 participants. In the first, people imagined emailing a caterer or a doctor, then learned the provider answered either within an hour or by the end of the day. Across both professions, the one-hour responders were rated more hireable, whether their profile carried a high star rating, a low one, or none at all. In the second, researchers swapped in photographers and compared a one-hour wait against a two-day wait. The one-hour group won again, and people described them as warmer and more competent, not just faster.

A third test asked whether a great message could outrun a slow clock. People read a caterer’s reply that was either generic (“I will have a plan in place and follow standard protocols”) or warm and specific (“I’ll make sure to stay in close contact as we plan so everything feels seamless”). The warmer message helped. But timing still mattered on its own: the caterer who sent that same warm message within an hour beat the one who sent it at day’s end.

Playing Hard to Get Signals Risk, Not Confidence

For decades, common wisdom in both dating and job hunting has held that a slower response makes someone look more in demand. This research suggests the opposite. People who waited longer for a reply weren’t more impressed. They were less convinced the person would actually show up for them later.

A quick reply, researchers found, works like a small preview of someone’s future behavior. People who got fast responses expected those providers to keep listening and stay attentive down the road, and that expectation, more than the speed itself, is what drove hiring decisions.

There’s a real limit to this effect, though. “Speed matters because people use it as information,” On Amir, a professor at UC San Diego’s Rady School of Management and a co-author of the study, said in a statement. “But there isn’t an equal sign between speed and responsiveness. Authenticity matters, too.” In follow-up experiments, the speed bonus shrank or disappeared once a reply seemed automatically generated or AI-written. Genuine speed helps. Hollow speed doesn’t.

There’s also a gap between what people say they want and what they actually reward. In an early pilot study, participants said a same-day reply would be perfectly fine. But when it came time to actually pick someone to hire, those same people consistently chose the faster responder anyway.

“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.”

A One-Hour Delay in Reply Speed Costs Freelancers Millions

Using Fiverr’s own reported revenue, researchers estimate these drop-off rates, applied across the whole platform, would cost freelancers roughly $195 million a year for a one-hour average delay and about $382 million for a full-day delay. Individual freelancers don’t experience an “average” loss, though. They either get the job or they don’t, and one slow reply can mean losing it outright.

A three-hour delay, the authors calculate, costs about as much in hiring odds as a 0.1-star drop on a five-star rating. That’s a steep price for something as ordinary as checking a message a little later than planned.

Even so, the takeaway holds up across a marketplace of millions and a string of controlled experiments alike. Playing it cool with a job message doesn’t read as confidence to the person waiting on the other end. It reads as a risk. As the authors put it, it is better to be speedy than sorry.
