"I regret accepting my job at my current company."

This statement was put to more than 10,000 employees of Uber, Microsoft, Facebook, Intel, and dozens of other Silicon Valley businesses to gauge how many agreed. A startling number of respondents said they did.

Nearly one-quarter--23.4 percent--said "yes," meaning they regret accepting their current job. Facebook had the lowest percentage of employees who responded affirmatively, at just 12 percent. Google and LinkedIn also fared well compared with other big names. The survey takers were users of Blind, an app and website on which employees can anonymously discuss tech, culture, and hiring issues, and seek advice about their careers.

On the other end of the spectrum was Snapchat. Of the 102 users who work at Snap and answered the question, 39.2 percent said they regretted taking their position at the company.

Early this year, Snap restructured its content teams. In March it laid off more than 120 engineers, and later let go of about 100 sales staff. The company went public in March of 2017, and since has built a "track record of grinding through executives, pursuing questionable strategies, and falling short of investors' financial expectations," wrote Shira Ovide in Bloomberg Opinion.

Close behind Snap were Oracle, where 34.1 percent of employees expressed regret over accepting their jobs, and Intel, where 32.0 percent expressed regret.

While Blind users are anonymous, each profile indicates the user's employer, which Blind has verified by the person's email address. Microsoft, Amazon, and Google have the most Blind users, with roughly 47,000, 31,000, and 12,000, respectively. 

Blind was founded in 2013 by Sunguk Moon, a veteran of the South Korean search giant Naver. While there, he'd noticed employees spoke candidly to each other on the company's intranet--and was dismayed when it was shut down after employees started talking about "critical and sensitive issues," he told The Mercury News. Blind has raised $6 million in venture capital funding and is building an ad-supported business. (Blind did not respond to a request for more information about its survey or the company itself.)

In an earlier survey, Blind tried to get a look at how prevalent self-doubt and insecurity are within large tech companies such as Airbnb, Apple, Google, Uber, and Lyft. It asked users: "Do you suffer from imposter syndrome?" More than half (58 percent) of the more than 10,000 people surveyed responded "yes."
