The time it takes to complete the average interview process globally increased by about a day this year, according to a report released by Glassdoor. The process takes 23.7 days thus far in 2017, up from 22.5 days in 2016.

The study found a wide range across countries in the number of days it takes to complete the interview process — from application submission to receiving an offer or rejection letter.

“Glassdoor’s study found that the more regulatory hurdles companies face within their local labor markets, the more difficult it will be to hire — and fire — employees, directly impacting how long it takes to fill open roles,” said Andrew Chamberlain, Glassdoor’s chief economist. “The longer it takes to hire, the greater the productivity loss for employers. And, the longer money is left on the table waiting for potential candidates.”

Additionally, employee background checks, skills tests and drug tests are becoming more commonly used, Chamberlain wrote in a blog post. This increased reliance on job candidate screening methods is a likely contributor to the recent trend toward longer interview times.

Brazil recorded the longest average hiring duration in 2017 with an average of 39.6 days, followed by France and Switzerland at 38.9 days and 37.6 days, respectively. By contrast, India reported the shortest interview processes at 16.1 days, followed by Israel and Romania at 16.9 days and 19.2 days, respectively.

In the US, the average hiring duration thus far in 2017 is 23.8 days, on par with the global average but up slightly from 22.9 days in 2014. However, not all cities within the US take the same amount of time to hire talent. Home to many federal government agencies, the interview process in Washington, DC, takes the longest at 32.2 days, followed by Albany, N.Y., and Richmond, Va., at 33.2 days and 27 days respectively. Conversely, the fastest cities to hire are Kansas City, at 16.9 days, followed by Oklahoma City and Akron, Ohio, at 17.9 and 18.0 days, respectively.

“While interviewing for one of the many government sector roles in Washington, DC, job candidates could undergo several extra steps that lengthen the overall interview process, including additional written and verbal exams or background checks to secure various levels of security clearances, among other requirements,” Chamberlain said.

Government ranked as the US industry with the longest interview process at 53.8 days, followed by aerospace and defense at 32.6 days and energy and utilities at 28.8 days. Jobs usually with high turnover rates had the shortest process, led by restaurants at 10.2 days, private security at 11.6 days and supermarkets at 12.3 days.

The study examined 83,921 interview reviews shared anonymously on Glassdoor from 25 countries with at least 100 reviews between Jan. 1 and June 13, 2017, in which job seekers recorded the length of a recent interview they experienced.
