I submitted an application, they responded by email 3 months later. First there was a phone interview, which lasted about 15 minutes and asked very basic first interview questions (tell me about yourself, why uber? tell me about being in a challenging situation and how you overcame it...etc). At the end of this interview they said the hiring process would be 3 weeks total and consist of 2 interviews, a homework assignment, and a group day project with existing employees and other applicants. The homework assignment was a very time-consuming marketing exercise full of hypothetical emails, tweets, blogs, and a "laundry list" of marketing ideas for the company. I kind of think they send this out to a bunch of hopeful applicants with no intention of hiring them just to get free ideas. I submitted the assignment within 3 days of the first interview and received an email a week later saying they are really busy and will get back to me soon. My next email was about a week after that saying it was not the right fit at this time.
