That’s the conclusion of a new research paper from Glassdoor Economic Research titled “Why Is Hiring Taking Longer?”. The study examined a sample of more than 340,000 job interview reviewsposted anonymously on Glassdoor. We studied whether hiring is moving faster or slower today compared to previous years—both in the U.S. and in five other countries around the world.
Where Do Interviews Take Longest?
The results were eye-opening. We found job interview processes vary dramatically around the world. What economists call “job matching” takes much longer in France, Germany, and the United Kingdomcompared to the U.S. and Canada—in some cases more than a week. The figure below shows the average time for hiring processes by country in 2014, which ranged from 22.1 days in Canada to 31.9 days in France.
Hiring Times Are On the Rise
In every country we examined, the time required for hiring processes is trending upward in recent years. Once we carefully controlled for other economic factors we found hiring times have grown by about 3.3 to 3.7 days on average since 2009. That trend remains even after accounting for shifts in job titles, companies, industries and job seeker demographics during that period. The figure below shows the overall upward trend in interview times around the world.
Hiring Policies Matter
What’s causing longer hiring processes? One factor seems to be the types of job interview “screening” methods used by employers. Each additional “screen”—such as requiring a group panel interview, background check, presentation, skills tests, and more—each add significantly to hiring times. For example, the simple act of requiring a group panel interview adds a statistical week to job interview processes.
The table below shows how much each interview screening method adds to hiring times, once we’ve statistically controlled for many other factors. Taken together, these small hiring delays from additional interview screens can add up.
Extra Days Added by Various Job Interview Screening Methods
| Interview Method | Average Days Added to Hiring Process |
| Phone Interview | +6.8 to +8.2 days |
| One-on-One Interview | +4.1 to +5.3 days |
| Group Panel Interview | +5.6 to +6.8 days |
| Presentation | +2.7 to +4.2 days |
| IQ Intelligence Test | +2.6 to +4.4 days |
| Job Skills Test | +0.6 to +1.5 days |
| Personality Test | +0.9 to +1.3 days |
| Drug Test | +0.3 to +0.8 days |
| Background Check | +3.1 to +3.4 days |
One possibility is that slower hiring times are actually good for companies. After all, more careful screening of job seekers may lead to better matches with candidates, especially for complex jobs that require hard-to-observe skills like creativity and judgment. Perhaps those longer hiring delays are simply a reflection of our economy’s shift toward high-skilled jobs in tech, health care and professional services.
On the other hand, there’s evidence that some hiring delays are probably wasteful. For example, we find larger companies take dramatically longer to hire candidates than small and mid-sized firms. Are bigger companies really getting much better job matches than their mid-sized competitors? Probably not. Instead, the slowing hiring processes at the world’s biggest employers—particularly for government employers—are likely due to creeping bureaucracy in the hiring process.
How Job Matching Affects the Economy
Delays in the hiring process can have a profound effect on people, companies and the economy. Longer hiring times can mean lost productivity in the workplace, foregone wages for job seekers, and longer unemployment spells in the economy.
While some of the growth in hiring delays probably reflects the need for more carefully screened job candidates, there’s also evidence that some delays could be avoided with more streamlined hiring processes.
As employers balance the tradeoff between screening and hiring delays, this study helps quantify the impact of today’s hiring policies on hiring times for the first time, and helps economists better understand the impact on job matching throughout the economy.
