HBR Research Finds Reply Speed Skews Hiring More Than Qualifications
The News
Research published in Management Science and summarised in Harvard Business Review analysed over 11 million transactions on the Fiverr marketplace and found that candidate response speed powerfully predicts hiring decisions — often more than qualifications. A one-hour delay made a candidate 46% less likely to be hired; a 24-hour delay made them 90% less likely. In one experiment, participants preferred a 4.25-star-rated caterer who replied within an hour over a 4.85-star caterer who replied at end of day. The effect held across job categories. Crucially, when responses were labelled or suspected as automated, the speed advantage disappeared — recruiters value speed as a signal of human warmth and competence, not just efficiency. Only 10% of managers said they expected a reply within an hour, yet their actual decisions behaved as if they did.
Why It Matters
This matters because most TA teams are layering automation into candidate communication without understanding the subconscious signals their recruiters rely on. If your scheduling bot or auto-responder is handling initial outreach, you may be neutralising the very speed signal your hiring managers unconsciously weight. More importantly, response-speed bias systematically disadvantages candidates who are employed, caregiving, or in different time zones — the people you often most want to hire. The research suggests this bias operates below conscious awareness: managers don't think they're filtering on speed, but the data says they are.
Taking Action
All action is situated in your corporate context. These are starting points, not prescriptions — choose what fits.

Who to talk with in your enterprise
Your head of talent acquisition: Discuss whether response-time data is tracked or visible in your ATS. If recruiters see timestamp data alongside candidate profiles, they may be making snap judgements without realising it. Your recruiting operations lead: Review where automated responses are deployed in your funnel — they may be helping efficiency but stripping signal that hiring managers actually use to make decisions.

What to take a closer look at
Pull time-to-first-response data from your ATS for the last 50 hires. Cross-reference response speed against hire quality at 90 days. If your fastest responders are also your best performers, the bias is harmless. If there's no correlation, you're likely screening out strong candidates who simply took longer to reply.
Reflect
What to think about more deeply
If response speed is a proxy for engagement, what exactly are you measuring — and are you comfortable hiring the candidate with the most free time rather than the best track record?
