I had a friend (super sharp guy, very very good in programming) long time ago - whenever he is bored, he'll schedule an interview with some company, clear the interview, and start negotiating the salary, just to see how much he could get. Once he gets an offer, he'll use that offer to drive up the offer from some other company that he interviewed with. Mind you, he had no intention of joining any of these companies, it was just a hobby/time-pass for him.

I used think he is a jerk for doing this, wasting everyone's time. After reading how companies treat the candidates, I am not so sure ...

Only the guys at the top are allowed to operate things like a business. For the people in the business itself, they are not allowed to operate like that silly

FYI sometime's its not the company itself (I have no idea with Uber) but rather a third party's ineptitude. I just had a series of phone interviews scheduled with candidates through an external vendor and multiple times they forgot to provide the candidate's contact information before the interview. I'm sure that's not what they told the candidate when I wasn't able to call them.

Given the company's history of misogyny, I'd say she lucked out.
