They'd just returned from their company trip to Vegas, he explained, and had been too busy dealing with the fallout from that 'crazy' trip to schedule interviews."The New York Times reported that the party was a drinking-fueled trip that included drug use, sexual assault, and an employee stealing a shuttle bus.Fowler said that a coworker later told her that the employees on the trip were "drunk out of their minds."Lack of female employeesWhen she interviewed at Uber, Fowler says she was told by interviewers about the large number of female engineers employed at the company. She remembers them telling her that "twenty-five percent!" of its engineers were women.But when she came to the Uber offices for her onsite interview, "the red flags continued.""The only women I could recall seeing during my visit were the recruiting coordinator and the janitor," Fowler writes.A team-building exercise gone wrongAt an event for new hires, Fowler says that there was a competition for "most interesting person." After groups discussed and chose a person to represent their group, the "most interesting" people gathered on the stage for a judge to choose the winner.Fowler was one of the nominees. The judge, a software engineering director, pointed to all the women on the stage, Fowler writes."Step down, and go back to your tables," Fowler recalls him telling all the women."There's no way, I thought to myself, that this guy just eliminated all of the women by accident, Fowler writes."I paused for a little too long, and he noticed I was still standing there onstage," Fowler says. "He shot me an angry look and beckoned me to return to my table. I stepped down and watched as he then picked the most interesting man.""Whistleblower: My Journey to Silicon Valley and Fight for Justice at Uber" is out now. Click here to read full news..
