During the conversation, the CEO said, “At Duolingo taxi drivers determine if candidates get hired.” Recalling an incident, he explained, “We were trying to hire a chief financial officer for a year and there was one candidate we all really liked.

Ahn recounted that the candidate had a strong resume and they looked like the right person for the job. However, the company decided not to hire the person after they were “pretty mean” to the cab driver on the way from the airport to the Duolingo office.

The CEO explained, “If they are going to me mean to the driver, they’re probably be mean to other people too, especially the people working under them” He added, “Sometimes the biggest interview answers never happen in the room, it happens in the car ride over when they think no one important is watching.

How did social media react?

The post prompted varied responses on social media. An individual posted, “That’s a smart move.” Another added, “100% says a lot about who you are - how you treat people when no one is watching!”

A third commented, “Love this.” A fourth wrote, “This is totally valid, it says so much about their character.”

Many, however, mentioned CEO Luis Von Ahn’s “AI-first” memo that went viral last year, conjuring worries of mass layoffs. The CEO of the $16.8 billion language app later clarified that it didn’t want to replace its “full-time employees” and didn’t intend to “lay off humans.”
